API

Collapse props

<table class="table table-bordered table-striped"> <thead> <tr> <th style="width: 100px;">name</th> <th style="width: 50px;">type</th> <th>default</th> <th>description</th> </tr> </thead> <tbody> <tr> <td>activeKey</td> <td>String|Array<String></td> <th>The first panel key</th> <td>current active Panel key</td> </tr> <tr> <td>className</td> <td>String or object</td> <th></th> <td>custom className to apply</td> </tr> <tr> <td>defaultActiveKey</td> <td>String|Array<String></td> <th>null</th> <td>default active key</td> </tr> <tr> <td>destroyOnHidden</td> <td>Boolean</td> <th>false</th> <td>If destroy the panel which not active, default false. </td> </tr> <tr> <td>accordion</td> <td>Boolean</td> <th>false</th> <td>accordion mode, default is null, is collapse mode</td> </tr> <tr> <td>onChange</td> <td>Function(key)</td> <th>noop</th> <td>called when collapse Panel is changed</td> </tr> <tr> <td>expandIcon</td> <td>(props: PanelProps) => ReactNode</td> <th></th> <td>specific the custom expand icon.</td> </tr> <tr> <td>collapsible</td> <td>'header' | 'icon' | 'disabled'</td> <th>-</th> <td>specify whether the panel of children is collapsible or the area of collapsible.</td> </tr> <tr> <td>items</td> <td> <a href="./src/interface.ts#ItemType">interface.ts#ItemType</a> </td> <th>-</th> <td>collapse items content</td> </tr> </tbody> </table>

If accordion is null or false, every panel can open. Opening another panel will not close any of the other panels. activeKey should be an string, if passing an array (the first item in the array will be used).

If accordion is true, only one panel can be open. Opening another panel will cause the previously opened panel to close. activeKey should be an string, if passing an array (the first item in the array will be used).

Collapse.Panel props

deprecated use items instead, will be removed in v4.0.0

<table class="table table-bordered table-striped"> <thead> <tr> <th style="width: 100px;">name</th> <th style="width: 200px;">type</th> <th>default</th> <th>description</th> </tr> </thead> <tbody> <tr> <td>header</td> <td>String or node</td> <th></th> <td>header content of Panel</td> </tr> <tr> <td>headerClass</td> <td>String</td> <th>' '</th> <td>custom className to apply to header</td> </tr> <tr> <td>showArrow</td> <td>boolean</td> <th>true</th> <td>show arrow beside header</td> </tr> <tr> <td>className</td> <td>String or object</td> <th></th> <td>custom className to apply</td> </tr> <tr> <td>classNames</td> <td>{ header?: string, body?: string }</td> <th></th> <td>Semantic structure className</td> </tr> <tr> <td>style</td> <td>object</td> <th></th> <td>custom style</td> </tr> <tr> <td>styles</td> <td>{ header?: React.CSSProperties, body?: React.CSSProperties }</td> <th></th> <td>Semantic structure styles</td> </tr> <tr> <td>openMotion</td> <td>object</td> <th></th> <td>set the animation of open behavior, [more](https://github.com/react-component/motion). Different with v2, closed pane use a `rc-collapse-content-hidden` class to set `display: none` for hidden.</td> </tr> <tr> <td>forceRender</td> <td>boolean</td> <th>false</th> <td>forced render of content in panel, not lazy render after clicking on header</td> </tr> <tr> <td>extra</td> <td>String | ReactNode</td> <th></th> <td>Content to render in the right of the panel header</td> </tr> <tr> <td>collapsible</td> <td>'header' | 'icon' | 'disabled'</td> <th>-</th> <td>specify whether the panel be collapsible or the area of collapsible.</td> </tr> </tbody> </table>

disabled is removed since 3.0.0, please use collapsible=disabled replace it.

key

If key is not provided, the panel's index will be used instead.

KeyBoard Event

By default, Collapse will listen onKeyDown(<3.7.0 onKeyPress) event with enter key to toggle panel's active state when collapsible is not disabled. If you want to disable this behavior, you can prevent the event from bubbling like this:

const App = () => {
  const items: CollapseProps['items'] = [
    {
      label: <input onKeyDown={(e) => e.stopPropagation()} />,
      children: 'content',
    },
    {
      label: (
        <div onKeyDown={(e) => e.stopPropagation()}>
          <CustomComponent />
        </div>
      ),
      children: 'content',
    },
    {
      label: 'title 2',
      children: 'content 2',
      collapsible: 'disabled',
    },
    {
      label: 'title 3',
      children: 'content 3',
      onItemClick: console.log,
    },
  ];

  return <Collapse items={items} />;
};
