  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">

    </Panel>
    <Panel header="This is panel header 2" key="2">
