## zh-CN
|
|
|
|
可以同时展开多个面板,这个例子默认展开了第一个。
|
|
|
|
## en-US
|
|
|
|
More than one panel can be expanded at a time, the first panel is initialized to be active in this case.

|
|
```jsx
|
|
import { Collapse, Select } from 'antd';

const { Option } = Select;

function callback(key) {
|
|
console.log(key);
|
|
}
