          <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>

          <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`

> `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:

```tsx | pure
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} />;
};
```
