折叠面板

可以同时展开多个面板，这个例子默认展开了第一个。

import { Collapse } from 'antd';
const Panel = Collapse.Panel;

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

const text = `
  A dog is a type of domesticated animal.
  Known for its loyalty and faithfulness,
  it can be found as a welcome guest in many households across the world.
`;

ReactDOM.render(
  <Collapse onChange={callback} accordion>
    <Panel header={'This is panel header 1'} key="1">
      <Collapse defaultActiveKey="1">
        <Panel header={'This is panel nest panel'} key="1">
          <p>{text}</p>
        </Panel>
      </Collapse>
    </Panel>
    <Panel header={'This is panel header 2'} key="2">
      <p>{text}</p>
    </Panel>
    <Panel header={'This is panel header 3'} key="3">
      <p>{text}</p>
    </Panel>
  </Collapse>
, mountNode);
