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).

|
#### 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:
|
|
|
|
```jsx
|
|
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} />;
|
|
};
|
|
```
|
|
|
|
