<script src="vue.js"></script>
<script src="vue-double-list/dist/vue-double-list.js"></script>

The plugin should be auto-installed. If not, you can install it manually with the instructions below:

Vue.use(DoubleList)

Usage

<double-list label="movies" :items="listItems" v-model="selectedItems"></double-list>

Props

Name	Type	Default	Description
items	Array	[]	List items for selection
label	String	""	Name describing items, used in UI for buttons, labels etc.
itemFilterKey	String	undefined	If items are objects, filter list on this item property
itemIdKey	String	undefined	If items are objects, use this item property for object identity
value	Array	[]	List of selected items, updated on @input

Example

With plain list items:

new Vue({
    el: '#vue',
    methods: {
        onInput: function() {
            console.log('Selection changed', this.selectedItems);
        }
    },
    data: {
        listItems: ['Back to the Future', 'The Future', 'Metropolis'],
        selectedItems: []
    }
})

With object list items, will keep selection by item's id when listItems is updated:

new Vue({
    el: '#vue',
    data: {
        listItems: [
            {id: 1, title: 'Back to the Future'}, 
            {id: 2, title: 'The Future'},
            {id: 3, title: 'Metropolis'}
        ],
        selectedItems: []
    }
})

To customize list item rendering, use named slot:

<double-list label="movies" :items="listItems" v-model="selectedItems">
<template slot="item" scope="props">
    {{ props.item.title }}
</template>
</double-list>

Plugin Development

Installation

The first time you create or clone your plugin, you need to install the default dependencies:

npm install

Watch and compile

This will run webpack in watching mode and output the compiled files in the dist folder.

npm run dev

Use it in another project

While developping, you can follow the install instructions of your plugin and link it into the project that uses it.

In the plugin folder:

npm link

In the other project folder:

npm link vue-double-list

This will install it in the dependencies as a symlink, so that it gets any modifications made to the plugin.

Publish to npm

You may have to login to npm before, with npm adduser. The plugin will be built in production mode before getting published on npm.

npm publish

Manual build

This will build the plugin into the dist folder in production mode.

npm run build
