react-native-picker-select

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

For iOS, by default we are wrapping an unstyled TextInput component. You can then pass down styles to customize it to your needs.

For Android, by default we are using the native Picker component. If you prefer, you can set useNativeAndroidPickerStyle to false, which will also render an unstyled TextInput component. You can then pass down styles to customize it to your needs.

For either platform, you can alternatively pass down a child element of your choice that will be wrapped in a touchable area.

disabled	Disables interaction with the component	boolean
value	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.	any
itemKey	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.	string, number

Styling

All properties mentioned below must be nested under the style prop. Examples of different styling options can be found on the example snack.

iOS-specific

• The component wraps a TextInput without styling. You can target the TextInput styling with inputIOS.
• Other styles that can be modified for iOS are named inputIOSContainer, placeholder, viewContainer, chevronContainer, chevron, chevronUp, chevronDown, chevronActive, done, modalViewTop, modalViewMiddle, and modalViewBottom

Android-specific

• The native Picker in its inactive state acts looks similar to a TextInput, but it has limitations on custom styling. Any styling that is possible can be applied via inputAndroid.
• You can add some styling customization to the active-state native Picker, but that requires modifying some xml files
• If you set the prop useNativeAndroidPickerStyle to false, the component will allow a few other style objects: inputAndroidContainer, placeholder, and inputAndroid
• Other styles that can be modified for Android are named headlessAndroidContainer and viewContainer

Icon

• If a component is passed in via the Icon prop - it will be rendered with { position: 'absolute', right: 0 } applied to its wrapping container. You can modify these values and add additional spacing to position the icon as needed by modifying iconContainer. You'll probably also want to add some paddingRight to your input styling to avoid any longer text appearing behind the icon.
• You can pass a component of your choosing (css, image, svg, etc..) for use as the icon. For ease of use, consider a library such as react-native-shapes or react-native-vector-icons.
• Examples of different icons and their usage can be found on the example snack.
