When To Use

• Can be used to group or hide complex regions to keep the page clean.
• Accordion is a special kind of Collapse, which allows only one panel to be expanded at a time.

// works when >= 5.6.0, recommended ✅
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.
`;

const items: CollapseProps['items'] = [
  {
    key: '1',
    label: 'This is panel header 1',
    children: <p>{text}</p>,
  },
  {
    key: '2',
    label: 'This is panel header 2',
    children: <p>{text}</p>,
  },
  {
    key: '3',
    label: 'This is panel header 3',
    children: <p>{text}</p>,
  },
];

<Collapse items={items} defaultActiveKey={['1']} />;

// works when <5.6.0 , deprecated when >=5.6.0  🙅🏻‍♀️

<Collapse defaultActiveKey={['1']} onChange={onChange}>
  <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">
    <p>{text}</p>
