Reorderable

Reorderable is a simple library that allows you to reorder items in LazyColumn, LazyRow, LazyVerticalGrid, LazyHorizontalGrid, LazyVerticalStaggeredGrid, and LazyHorizontalStaggeredGrid as well as Column and Row in Jetpack Compose and Compose Multiplatform with drag and drop.

The latest demo app APK can be found in the releases section under the "Assets" section of the latest release.

Features

Supports Compose Multiplatform (Android, iOS, Desktop/JVM, Wasm, JS)
Supports items of different sizes
Some items can be made non-reorderable
Supports dragging immediately or long press to start dragging
Supports section headers and footers
Scrolls when dragging to the edge of the screen. (unavailable for Column and Row) The scroll speed is based on the distance from the edge of the screen.
Uses the new Modifier.animateItemPlacement API to animate item movement in LazyColumn, LazyRow, LazyVerticalGrid, LazyHorizontalGrid, LazyVerticalStaggeredGrid, and LazyHorizontalStaggeredGrid
Supports using a child of an item as the drag handle

Usage

Version Catalog

If you're using Version Catalog, add the following to your libs.versions.toml file:

[versions]
#...
reorderable = "2.3.3"

[libraries]
#...
reorderable = { module = "sh.calvin.reorderable:reorderable", version.ref = "reorderable" }

or

[libraries]
#...
reorderable = { module = "sh.calvin.reorderable:reorderable", version = "2.3.3" }

then

dependencies {
    // ...
    implementation(libs.reorderable)
}

Gradle

If you're using Gradle instead, add the following to your build.gradle file:

Kotlin DSL

dependencies {
    // ...
    implementation("sh.calvin.reorderable:reorderable:2.3.3")
}

Groovy DSL

dependencies {
    implementation 'sh.calvin.reorderable:reorderable:2.3.3'
}

Examples

See demo app code for more examples.

`LazyColumn`

Find more examples in SimpleReorderableLazyColumnScreen.kt, SimpleLongPressHandleReorderableLazyColumnScreen.kt and ComplexReorderableLazyColumnScreen.kt in the demo app.

Simple Example

To use this library with LazyColumn, follow this basic structure:

val lazyListState = rememberLazyListState()
val reorderableLazyListState = rememberReorderableLazyListState(lazyListState) { from, to ->
    // Update the list
}

LazyColumn(state = lazyListState) {
    items(list, key = { /* item key */ }) {
        ReorderableItem(reorderableLazyListState, key = /* item key */) { isDragging ->
            // Item content

            IconButton(
                modifier = Modifier.draggableHandle(),
                /* ... */
            )
        }
    }
}

Complete Example (with haptic feedback)

Note

val view = LocalView.current and View.performHapticFeedback are only available in Android. Comment out these lines if you are using this library in a multiplatform project.

val view = LocalView.current

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyListState = rememberLazyListState()
val reorderableLazyListState = rememberReorderableLazyListState(lazyListState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyColumn(
    modifier = Modifier.fillMaxSize(),
    state = lazyListState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) {
        ReorderableItem(reorderableLazyListState, key = it) { isDragging ->
            val elevation by animateDpAsState(if (isDragging) 4.dp else 0.dp)

            Surface(shadowElevation = elevation) {
                Row {
                    Text(it, Modifier.padding(horizontal = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }
                }
            }
        }
    }
}

Section Headers and Footers or Multiple Lists

The from.index and to.index in onMove are the indices of the items in the LazyColumn. If you have section headers or footers, you may need to adjust the indices accordingly. For example:

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyListState = rememberLazyListState()
val reorderableLazyColumnState = rememberReorderableLazyListState(lazyListState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index - 1, removeAt(from.index - 1))
    }
}

LazyColumn(
    state = lazyListState,
    // ...
) {
    item {
        Text("Header")
    }

    items(list, key = { item -> item.id }) { item ->
        ReorderableItem(reorderableLazyColumnState, item.id) {
            // ...
        }
    }
}

Passing `Modifier.draggableHandle` to a Child Composable

Since Modifier.draggableHandle and Modifier.longPressDraggableHandle can only be used in ReorderableCollectionItemScope, you may need to pass ReorderableCollectionItemScope to a child composable. For example:

@Composable
fun List() {
    // ...

    LazyColumn(state = lazyListState) {
        items(list, key = { /* item key */ }) {
            ReorderableItem(reorderableLazyListState, key = /* item key */) { isDragging ->
                // Item content

                DragHandle(this)
            }
        }
    }
}

@Composable
fun DragHandle(scope: ReorderableCollectionItemScope) {
    IconButton(
        modifier = with(scope) {
            Modifier.draggableHandle()
        },
        /* ... */
    )
}

Scroll Trigger Padding

If your LazyColumn displays under navigation bar or notification bar, you may want to add scrollThresholdPadding to rememberReorderableLazyListState to move the scroll trigger area out from under the navigation bar or notification bar.

val reorderableLazyListState = rememberReorderableLazyListState(
    lazyListState = lazyListState,
    scrollThresholdPadding = WindowInsets.systemBars.asPaddingValues(),
) { from, to ->
    ...
}

Use with `Card`

If you want to use the material3's Clickable Card, you can create a MutableInteractionSource and pass it to both the Card and the Modifier.draggableHandle (or Modifier.longPressDraggableHandle), Modifier.draggableHandle will emit drag events to the MutableInteractionSource so that the Card can respond to the drag events:

val view = LocalView.current

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyListState = rememberLazyListState()
val reorderableLazyListState = rememberReorderableLazyListState(lazyListState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyColumn(
    modifier = Modifier.fillMaxSize(),
    state = lazyListState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) { item ->
        ReorderableItem(reorderableLazyListState, key = item) {
            val interactionSource = remember { MutableInteractionSource() }

            Card(
                onClick = {},
                interactionSource = interactionSource,
            ) {
                Row {
                    Text(item, Modifier.padding(horizontal = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                            interactionSource = interactionSource,
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }
                }
            }
        }
    }
}

LazyRow

See SimpleReorderableLazyRowScreen.kt and ComplexReorderableLazyRowScreen.kt in the demo app.

Simple Example

To use this library with LazyRow, follow this basic structure:

val lazyListState = rememberLazyListState()
val reorderableLazyListState = rememberReorderableLazyListState(lazyListState) { from, to ->
    // Update the list
}

LazyRow(state = lazyListState) {
    items(list, key = { /* item key */ }) {
        ReorderableItem(reorderableLazyListState, key = /* item key */) { isDragging ->
            // Item content

            IconButton(
                modifier = Modifier.draggableHandle(),
                /* ... */
            )
        }
    }
}

val lazyListState = rememberLazyListState()
val reorderableLazyListState = rememberReorderableLazyListState(lazyListState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyRow(
    modifier = Modifier.fillMaxSize(),
    state = lazyListState,
    contentPadding = PaddingValues(8.dp),
    horizontalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) {
        ReorderableItem(reorderableLazyListState, key = it) { isDragging ->
            val elevation by animateDpAsState(if (isDragging) 4.dp else 0.dp)

            Surface(shadowElevation = elevation) {
                Column {
                    Text(it, Modifier.padding(vertical = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }
                }
            }
        }
    }
}

Section Headers and Footers or Multiple Lists

The from.index and to.index in onMove are the indices of the items in the LazyRow. If you have section headers or footers, you may need to adjust the indices accordingly. For example:

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyListState = rememberLazyListState()
val reorderableLazyRowState = rememberReorderableLazyListState(lazyListState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index - 1, removeAt(from.index - 1))
    }
}

LazyRow(
    state = lazyListState,
    // ...
) {
    item {
        Text("Header")
    }

    items(list, key = { item -> item.id }) { item ->
        ReorderableItem(reorderableLazyRowState, item.id) {
            // ...
        }
    }
}

Passing `Modifier.draggableHandle` to a Child Composable

Since Modifier.draggableHandle and Modifier.longPressDraggableHandle can only be used in ReorderableCollectionItemScope, you may need to pass ReorderableCollectionItemScope to a child composable. For example:

@Composable
fun List() {
    // ...

    LazyRow(state = lazyListState) {
        items(list, key = { /* item key */ }) {
            ReorderableItem(reorderableLazyListState, key = /* item key */) { isDragging ->
                // Item content

                DragHandle(this)
            }
        }
    }
}

@Composable
fun DragHandle(scope: ReorderableCollectionItemScope) {
    IconButton(
        modifier = with(scope) {
            Modifier.draggableHandle()
        },
        /* ... */
    )
}

        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyRow(
    modifier = Modifier.fillMaxSize(),
    state = lazyListState,
    contentPadding = PaddingValues(8.dp),
    horizontalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) { item ->
        ReorderableItem(reorderableLazyListState, key = item) {
            val interactionSource = remember { MutableInteractionSource() }

                            },
                            interactionSource = interactionSource,
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }

        }
    }
}

`LazyVerticalGrid`

Simple Example

To use this library with LazyVerticalGrid, follow this basic structure:

val lazyGridState = rememberLazyGridState()
val reorderableLazyGridState = rememberReorderableLazyGridState(lazyGridState) { from, to ->
    // Update the list
}

LazyVerticalGrid(state = lazyGridState) {
    items(list, key = { /* item key */ }) {
        ReorderableItem(reorderableLazyGridState, key = /* item key */) { isDragging ->
            // Item content

            IconButton(
                modifier = Modifier.draggableHandle(),
                /* ... */
            )
        }

LazyVerticalGrid(
    columns = GridCells.Adaptive(minSize = 96.dp),
    modifier = Modifier.fillMaxSize(),
    state = lazyGridState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
    horizontalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) {
        ReorderableItem(reorderableLazyGridState, key = it) { isDragging ->
            val elevation by animateDpAsState(if (isDragging) 4.dp else 0.dp)

                }
            }
        }
    }
}

Section Headers and Footers or Multiple Lists

The from.index and to.index in onMove are the indices of the items in the LazyVerticalGrid. If you have section headers or footers, you may need to adjust the indices accordingly. For example:

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyGridState = rememberLazyGridState()
val reorderableLazyGridState = rememberReorderableLazyGridState(lazyGridState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index - 1, removeAt(from.index - 1))
    }
}

LazyVerticalGrid(
    state = lazyGridState,
    // ...
) {
    item {
        Text("Header")
    }

    items(list, key = { item -> item.id }) { item ->
        ReorderableItem(reorderableLazyGridState, item.id) {
            // ...
        }
    }
}

Passing `Modifier.draggableHandle` to a Child Composable

Since Modifier.draggableHandle and Modifier.longPressDraggableHandle can only be used in ReorderableCollectionItemScope, you may need to pass ReorderableCollectionItemScope to a child composable. For example:

@Composable
fun Grid() {
    // ...

    LazyVerticalGrid(state = lazyGridState) {
        items(Grid, key = { /* item key */ }) {
            ReorderableItem(reorderableLazyGridState, key = /* item key */) { isDragging ->
                // Item content

                DragHandle(this)
            }
        }
    }
}

@Composable
fun DragHandle(scope: ReorderableCollectionItemScope) {
    IconButton(
        modifier = with(scope) {
            Modifier.draggableHandle()
        },
        /* ... */
    )
}

Scroll Trigger Padding

If your LazyVerticalGrid displays under navigation bar or notification bar, you may want to add scrollThresholdPadding to rememberReorderableLazyGridState to move the scroll trigger area out from under the navigation bar or notification bar.

val reorderableLazyGridState = rememberReorderableLazyGridState(
    lazyGridState = lazyGridState,
    scrollThresholdPadding = WindowInsets.systemBars.asPaddingValues(),
) { from, to ->
    ...
}

Use with `Card`

If you want to use the material3's Clickable Card, you can create a MutableInteractionSource and pass it to both the Card and the Modifier.draggableHandle (or Modifier.longPressDraggableHandle), Modifier.draggableHandle will emit drag events to the MutableInteractionSource so that the Card can respond to the drag events:

val view = LocalView.current

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyGridState = rememberLazyGridState()
val reorderableLazyGridState = rememberReorderableLazyGridState(lazyGridState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyVerticalGrid(
    columns = GridCells.Adaptive(minSize = 96.dp),
    modifier = Modifier.fillMaxSize(),
    state = lazyGridState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
    horizontalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) { item ->
        ReorderableItem(reorderableLazyGridState, key = item) {
            val interactionSource = remember { MutableInteractionSource() }

            Card(
                onClick = {},
                interactionSource = interactionSource,
            ) {
                Row {
                    Text(item, Modifier.padding(horizontal = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                            interactionSource = interactionSource,
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }
                }
            }
        }
    }
}

            IconButton(
                modifier = Modifier.draggableHandle(),
                /* ... */
            )
        }
    }
}

val view = LocalView.current and View.performHapticFeedback are only available in Android. Comment out these lines if you are using this library in a multiplatform project.

val view = LocalView.current

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyGridState = rememberLazyGridState()
val reorderableLazyGridState = rememberReorderableLazyGridState(lazyGridState) { from, to ->

    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyHorizontalGrid(
    rows = GridCells.Adaptive(minSize = 96.dp),
    modifier = Modifier.fillMaxSize(),
    state = lazyGridState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
    horizontalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) {
        ReorderableItem(reorderableLazyGridState, key = it) { isDragging ->
            val elevation by animateDpAsState(if (isDragging) 4.dp else 0.dp)

            Surface(shadowElevation = elevation) {
                Row {
                    Text(it, Modifier.padding(horizontal = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                        ),
                        onClick = {},
                    ) {

                    }
                }
            }
        }
    }
}

Section Headers and Footers or Multiple Lists

The from.index and to.index in onMove are the indices of the items in the LazyHorizontalGrid. If you have section headers or footers, you may need to adjust the indices accordingly. For example:

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyGridState = rememberLazyGridState()
val reorderableLazyGridState = rememberReorderableLazyGridState(lazyGridState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index - 1, removeAt(from.index - 1))
    }
}

LazyHorizontalGrid(
    state = lazyGridState,
    // ...
) {
    item {
        Text("Header")
    }

    items(list, key = { item -> item.id }) { item ->
        ReorderableItem(reorderableLazyGridState, item.id) {
            // ...
        }
    }
}

Passing `Modifier.draggableHandle` to a Child Composable

Since Modifier.draggableHandle and Modifier.longPressDraggableHandle can only be used in ReorderableCollectionItemScope, you may need to pass ReorderableCollectionItemScope to a child composable. For example:

@Composable
fun Grid() {
    // ...

    LazyHorizontalGrid(state = lazyGridState) {
        items(Grid, key = { /* item key */ }) {
            ReorderableItem(reorderableLazyGridState, key = /* item key */) { isDragging ->
                // Item content

                DragHandle(this)
            }
        }
    }
}

@Composable
fun DragHandle(scope: ReorderableCollectionItemScope) {
    IconButton(
        modifier = with(scope) {
            Modifier.draggableHandle()
        },
        /* ... */
    )
}

Scroll Trigger Padding

If your LazyHorizontalGrid displays under navigation bar or notification bar, you may want to add scrollThresholdPadding to rememberReorderableLazyGridState to move the scroll trigger area out from under the navigation bar or notification bar.

val reorderableLazyGridState = rememberReorderableLazyGridState(
    lazyGridState = lazyGridState,
    scrollThresholdPadding = WindowInsets.systemBars.asPaddingValues(),
) { from, to ->
    ...
}

    list = list.toMutableList().apply {
        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyHorizontalGrid(
    rows = GridCells.Adaptive(minSize = 96.dp),
    modifier = Modifier.fillMaxSize(),
    state = lazyGridState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
    horizontalArrangement = Arrangement.spacedBy(8.dp),
) {
    items(list, key = { it }) { item ->
        ReorderableItem(reorderableLazyGridState, key = item) {
            val interactionSource = remember { MutableInteractionSource() }

            Card(
                onClick = {},
                interactionSource = interactionSource,
            ) {
                Row {
                    Text(item, Modifier.padding(horizontal = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                            interactionSource = interactionSource,
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }

                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }
                }
            }
        }
    }
}

Section Headers and Footers or Multiple Lists

The from.index and to.index in onMove are the indices of the items in the LazyHorizontalStaggeredGrid. If you have section headers or footers, you may need to adjust the indices accordingly. For example:

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyStaggeredGridState = rememberLazyStaggeredGridState()
val reorderableLazyStaggeredGridState = rememberReorderableLazyStaggeredGridState(lazyStaggeredGridState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index - 1, removeAt(from.index - 1))
    }
}

LazyHorizontalStaggeredGrid(
    state = lazyStaggeredGridState,
    // ...
) {
    item {
        Text("Header")
    }

    items(list, key = { item -> item.id }) { item ->
        ReorderableItem(reorderableLazyStaggeredGridState, item.id) {
            // ...
        }
    }
}

Passing `Modifier.draggableHandle` to a Child Composable

Since Modifier.draggableHandle and Modifier.longPressDraggableHandle can only be used in ReorderableCollectionItemScope, you may need to pass ReorderableCollectionItemScope to a child composable. For example:

@Composable
fun Grid() {
    // ...

    LazyHorizontalStaggeredGrid(state = lazyStaggeredGridState) {
        items(list, key = { /* item key */ }) {
            ReorderableItem(reorderableLazyStaggeredGridState, key = /* item key */) { isDragging ->
                // Item content

                DragHandle(this)
            }
        }
    }
}

@Composable
fun DragHandle(scope: ReorderableCollectionItemScope) {
    IconButton(
        modifier = with(scope) {
            Modifier.draggableHandle()
        },
        /* ... */
    )
}

Scroll Trigger Padding

If your LazyHorizontalStaggeredGrid displays under navigation bar or notification bar, you may want to add scrollThresholdPadding to rememberReorderableLazyStaggeredGridState to move the scroll trigger area out from under the navigation bar or notification bar.

val reorderableLazyStaggeredGridState = rememberReorderableLazyStaggeredGridState(
    lazyStaggeredGridState = lazyStaggeredGridState,
    scrollThresholdPadding = WindowInsets.systemBars.asPaddingValues(),
) { from, to ->
    ...
}

Use with `Card`

If you want to use the material3's Clickable Card, you can create a MutableInteractionSource and pass it to both the Card and the Modifier.draggableHandle (or Modifier.longPressDraggableHandle), Modifier.draggableHandle will emit drag events to the MutableInteractionSource so that the Card can respond to the drag events:

val view = LocalView.current

var list by remember { mutableStateOf(List(100) { "Item $it" }) }
val lazyStaggeredGridState = rememberLazyStaggeredGridState()
val reorderableLazyStaggeredGridState = rememberReorderableLazyStaggeredGridState(lazyStaggeredGridState) { from, to ->
    list = list.toMutableList().apply {
        add(to.index, removeAt(from.index))
    }

    view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
}

LazyHorizontalStaggeredGrid(
    rows = StaggeredGridCells.Adaptive(minSize = 96.dp),
    modifier = Modifier.fillMaxSize(),
    state = lazyStaggeredGridState,
    contentPadding = PaddingValues(8.dp),
    verticalArrangement = Arrangement.spacedBy(8.dp),
    horizontalItemSpacing = 8.dp,
) {
    items(list, key = { it }) { item ->
        ReorderableItem(reorderableLazyStaggeredGridState, key = item) {
            val interactionSource = remember { MutableInteractionSource() }

            Card(
                onClick = {},
                interactionSource = interactionSource,
            ) {
                Row {
                    Text(item, Modifier.padding(horizontal = 8.dp))
                    IconButton(
                        modifier = Modifier.draggableHandle(
                            onDragStarted = {
                                view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                            },
                            onDragStopped = {
                                view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                            },
                            interactionSource = interactionSource,
                        ),
                        onClick = {},
                    ) {
                        Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                    }
                }
            }
        }
    }
}

`Column`

Find more examples in ReorderableColumnScreen.kt and LongPressHandleReorderableColumnScreen.kt in the demo app.

Simple Example

To use this library with Column, follow this basic structure:

ReorderableColumn(
    list = list,
    onSettle = { fromIndex, toIndex ->
        // Update the list
    },
) { index, item, isDragging ->
    key(item.id) {
        // Item content

        IconButton(modifier = Modifier.draggableHandle(), /* ... */)
    }
}

Complete Example (with haptic feedback)

Note

val view = LocalView.current and View.performHapticFeedback are only available in Android. Comment out these lines if you are using this library in a multiplatform project.

val view = LocalView.current

var list by remember { mutableStateOf(List(4) { "Item $it" }) }

ReorderableColumn(
    modifier = Modifier
        .fillMaxSize()
        .padding(8.dp),
    list = list,
    onSettle = { fromIndex, toIndex ->
        list = list.toMutableList().apply {
            add(toIndex, removeAt(fromIndex))
        }
    },
    onMove = {
        view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
    },
    verticalArrangement = Arrangement.spacedBy(8.dp),
) { _, item, isDragging ->
    key(item) {
        val elevation by animateDpAsState(if (isDragging) 4.dp else 0.dp)

        Surface(shadowElevation = elevation) {
            Row {
                Text(item, Modifier.padding(horizontal = 8.dp))
                IconButton(
                    modifier = Modifier.draggableHandle(
                        onDragStarted = {
                            view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                        },
                        onDragStopped = {
                            view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                        },
                    ),
                    onClick = {},
                ) {
                    Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                }
            }
        }
    }
}

Passing `Modifier.draggableHandle` to a Child Composable

Since Modifier.draggableHandle and Modifier.longPressDraggableHandle can only be used in ReorderableScope, you may need to pass ReorderableScope to a child composable. For example:

@Composable
fun List() {
    // ...

    ReorderableColumn(
        list = list,
        onSettle = { fromIndex, toIndex ->
            // Update the list
        },
    ) { index, item, isDragging ->
        key(item.id) {
            // Item content

            DragHandle(this)
        }
    }
}

@Composable
fun DragHandle(scope: ReorderableScope) {
    IconButton(modifier = with(scope) { Modifier.draggableHandle() }, /* ... */)
}

Use with `Card`

If you want to use the material3's Clickable Card, you can create a MutableInteractionSource and pass it to both the Card and the Modifier.draggableHandle (or Modifier.longPressDraggableHandle), Modifier.draggableHandle will emit drag events to the MutableInteractionSource so that the Card can respond to the drag events:

        .fillMaxSize()
        .padding(8.dp),
    list = list,
    onSettle = { fromIndex, toIndex ->
        list = list.toMutableList().apply {
            add(toIndex, removeAt(fromIndex))
        }
    },
    onMove = {
        view.performHapticFeedback(HapticFeedbackConstants.SEGMENT_FREQUENT_TICK)
    },
    verticalArrangement = Arrangement.spacedBy(8.dp),
) { _, item, _ ->
    key(item) {
        val interactionSource = remember { MutableInteractionSource() }

        Card(
            onClick = {},
            interactionSource = interactionSource,
        ) {
            Row {
                Text(item, Modifier.padding(horizontal = 8.dp))
                IconButton(
                    modifier = Modifier.draggableHandle(
                        onDragStarted = {
                            view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                        },
                        onDragStopped = {
                            view.performHapticFeedback(HapticFeedbackConstants.GESTURE_END)
                        },
                        interactionSource = interactionSource,
                    ),
                    onClick = {},

                }
            }
        }
    }
}

`Row`

See ReorderableRowScreen.kt in the demo app.

Simple Example

To use this library with Row, follow this basic structure:

ReorderableRow(
    list = list,
    onSettle = { fromIndex, toIndex ->
        // Update the list
    },
) { index, item, isDragging ->
    key(item.id) {
        // Item content

        IconButton(modifier = Modifier.draggableHandle(), /* ... */)
    }
}

            // Item content

            DragHandle(this)

                IconButton(

                        onDragStarted = {
                            view.performHapticFeedback(HapticFeedbackConstants.DRAG_START)
                        },
                        onDragStopped = {

                        interactionSource = interactionSource,
                    ),
                    onClick = {},
                ) {
                    Icon(Icons.Rounded.DragHandle, contentDescription = "Reorder")
                }
            }
        }
    }
}

Accessibility

See the demo app for examples of how to make the reorderable list accessible.

If the items in the list do not contain any button besides the drag handle, I recommend adding "Move Up"/"Move Down"/"Move Left"/"Move Right" actions to the TalkBack menu in each item via SemanticsPropertyReceiver.customActions and applying Modifier.clearAndSetSemantics to the drag handle button to make the drag handle button not focusable for TalkBack. For more information, see Key steps to improve Compose accessibility.

FAQ

When `onMove` is called to move items, the dragging item flickers/jumps/flashes.

Note

This assumes you're using version 2.0.3 or later of this library.

The onMove function expects the list to be updated before it returns. If the list is updated after onMove returns, the dragging item will flicker. To fix this, update the list before returning from onMove.

val reorderableLazyXXXXState = rememberReorderableLazyXXXXState(listState) { from, to ->
    // do NOT wrap the updateList call in `launch`
    updateList(from, to)
}

suspend fun updateList(from: Int, to: Int) {
    // long update operation
}

If you can't keep the list update inside onMove, you can use a channel to communicate between onMove and the list update composition. Here's an example:

val listUpdatedChannel = remember { Channel<Unit>() }
val reorderableLazyXXXXState = rememberReorderableLazyXXXXState(listState) { from, to ->
    // clear the channel
    listUpdatedChannel.tryReceive()

    // update the list

    // wait for the list to be updated
    listUpdatedChannel.receive()
}

LaunchedEffect(list) {
    // notify the list is updated
    listUpdatedChannel.trySend(Unit)
}

When moving the top item, the list flickers/jumps/flashes.

See issue #4. This problem will be fixed once Compose Foundation v1.7.0 is released.
