react-native-picker-select

A Picker component for React Native which emulates the native <select> interfaces for iOS and Android

For iOS, we are wrapping a TextInput component. You can pass down your custom styling to match your other inputs.

For Android, we are using the native Picker component, but adding a pseudo-underline to emulate a typical TextInput. Additional styling can be passed down also to further customize the appearance.

For either platform, you can alternatively pass down a child element that will be wrapped in a touchable area, triggering the picker.

Props

Name	Type	Description	Required?	iOS / Android
onValueChange	function	Callback which returns value, index	Y	Both
items	array	The items for the component to render - Each item should be in the following format: {label: 'Orange', value: 'orange', key: 'orange', color: 'orange'} - The label and the value are required - The key and color are optional - The key will be set to the label if not included - The value can be any data type	Y	Both
placeholder	object	- An override for the default placeholder object with a label of Select an item... and a value of null - An empty object can be used if you'd like to disable the placeholder entirely	N	Both
disabled	boolean	Disables interaction with the component	N	Both
value	any	Will attempt to locate a matching item from the items array by checking each item's value property. If found, it will update the component to show that item as selected. If the value is not found, it will default to the first item.	N	Both
itemKey	string, number	Will attempt to locate a matching item from the items array by checking each item's key property. If found, it will update the component to show that item as selected. If the key is not found, it will attempt to find a matching item by value as above.	N	Both
style	object	Style overrides for most parts of the component. More details below.	N	Both
hideIcon	boolean	Hides the floating downward arrow on the right side of the input box	N	Both
pickerProps	object	Additional props to pass to the Picker (some props are used in core functionality so use this carefully)	N	Both
placeholderTextColor	color	Overrides the default placeholder color shown	N	iOS
useNativeAndroidPickerStyle	boolean	DEFAULTS TO TRUE. The component defaults to using the native React Native Picker in it's un-selected state. Setting this flag to false will mimic the default iOS presentation where a tappable TextInput is displayed. See more in the styling section.	N	Android
hideDoneBar	boolean	Hides the bar with tabbing arrows and Done link to exit the modal. While this is typical on select elements on the web, the interface guidelines does not include it.	N	iOS

Styling

• iOS
  • The component wraps a TextInput without styling. In the style prop, pass a style object named inputIOS to style the input
  • Alternatively, you can pass children (such as a custom button or input) for the component to wrap
  • Other styles that can be modified for iOS are named inputIOSContainer, viewContainer, icon, chevron, chevronUp, chevronDown, chevronActive, done, modalViewTop, modalViewMiddle, and modalViewBottom
• Android
  • The default Picker component acts similiarly to a TextInput until it is tapped, although it does not include an underline
  • We emulate a typical underline, which can be modified with a style object named underline
  • The main input can be modified with the style object named inputAndroid
  • Alternatively, you can pass children (such as a custom button or input) for the component to wrap
  • Other styles that can be modified for Android are named headlessAndroidContainer and viewContainer
  • If you set the prop useNativeAndroidPickerStyle to false, the component will allow two other style objects: inputAndroidContainer and inputAndroid
