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).

showArrow	boolean	true	show arrow beside header

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} />;
};
