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.

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.

changelog

6.1.0

New
  • Opened up placeholder on style object for modification (#119) (#155). The placeholderTextColor prop is now deprecated, as this style object allows for additional properties.

6.0.0

Breaking Changes

  • In order to make this component less opinionated, especially in terms of style, we have removed the default dropdown arrow icon in leiu of a more flexible Icon prop which will render a component - allowing you to insert your own css, image, svg, or icon from any library of your choosing. Due to this change, the noIcon prop has been removed. To replicate the arrow from previous versions, see the last example / see the styling section in the README for more details.
  • In Android, we no longer insert a psuedo-underline by default - as the default input style in React Native sets the underline color to transparent since this PR - which landed in 0.56. You can add this back in fairly easily, either by using the textInputProps prop or by adding a border on one of the wrapping container elements - all depending on your personal usage of the component.
  • Some of the default styles of the iOS "Done bar" have been tweaked and streamlined
  • if using useNativeAndroidPickerStyle={false}, the outer container is now only headlessAndroidContainer without viewContainer wrapping it
