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 } from 'parkball';

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 defaultActiveKey={['1']} onChange={callback}>
    <Panel header="This is panel header 1" key="1">
      <p>{text}</p>
    </Panel>
    <Panel header="This is panel header 2" key="2">
      <p>{text}</p>
    </Panel>
    <Panel header="This is panel header 3" key="3" disabled>
      <p>{text}</p>
    </Panel>
  </Collapse>,
  mountNode);

<style>
