@fluentui-react-native/experimental-expander v0.8.1

@fluentui-react-native/experimental-expander

This package provides a FluentUI React Native implementation of the WinUI 2.6 Expander control.

This component is only supported on Windows.

Getting started

$ npm install @fluentui-react-native/experimental-expander --save

or

$ yarn add @fluentui-react-native/experimental-expander

After the package has been installed, run the following command to link the package.

npx react-native autolink-windows

Usage

Import Expander from @fluentui-react-native/experimental-expander

import { Expander } from @fluentui-react-native/experimental-expander

Add Expander as follows:

<Expander collapsedHeight={50} expandedHeight={100}>
  <Text>Text in the header</Text>
  <Text>Text in the content</Text>
</Expander>

The first child element of Expander will be assigned to the header, and the second child element will be assigned to the content. If you would like multiple components in the header or the content, wrap them in View as follows:

<Expander collapsedHeight={75} expandedHeight={150}>
  <View>
    <Text>Text in the header</Text>
    <Text>Second line of text in the header<Text>
  </View>
  <View>
    <Text>Text in the content</Text>
    <Text>Second line of text in the content<Text>
  </View>
</Expander>

Important notes

• collapsedHeight and expandedHeight must be set for Expander to display correctly. There is no need to set the height prop.
• Non-native components within the header will not be interactable (i.e. if there is a Button in the header, and you press it, the Expander will expand, and the Button functionality will not be performed). We recommend using react-native-xaml controls in the header if you would like an interactive control that does not have a native implementation.
