代码演示

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;
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,
);

手风琴

手风琴，每次只打开一个 tab。

import { Collapse } from 'antd';
const { Panel } = Collapse;
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 accordion>
    <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>
    </Panel>
  </Collapse>,
  mountNode,
);

面板嵌套

嵌套折叠面板。

import { Collapse } from 'antd';
const { Panel } = Collapse;
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}>
    <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,
);

简洁风格

一套没有边框的简洁样式。

import { Collapse } from 'antd';
const { Panel } = Collapse;
const text = (
  <p style={{ paddingLeft: 24 }}>
    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.
  </p>
);
ReactDOM.render(
  <Collapse bordered={false} defaultActiveKey={['1']}>
    <Panel header="This is panel header 1" key="1">
      {text}
    </Panel>
    <Panel header="This is panel header 2" key="2">
      {text}
    </Panel>
    <Panel header="This is panel header 3" key="3">
      {text}
    </Panel>
  </Collapse>,
  mountNode,
);

自定义面板

自定义各个面板的背景色、圆角、边距和图标。

import { Collapse } from 'antd';
import { CaretRightOutlined } from '@ant-design/icons';
const { Panel } = Collapse;
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
    bordered={false}
    defaultActiveKey={['1']}
    expandIcon={({ isActive }) => <CaretRightOutlined rotate={isActive ? 90 : 0} />}
    className="site-collapse-custom-collapse"
  >
    <Panel header="This is panel header 1" key="1" className="site-collapse-custom-panel">
      <p>{text}</p>
    </Panel>
    <Panel header="This is panel header 2" key="2" className="site-collapse-custom-panel">
      <p>{text}</p>
    </Panel>
    <Panel header="This is panel header 3" key="3" className="site-collapse-custom-panel">
      <p>{text}</p>
    </Panel>
  </Collapse>,
  mountNode,
);

.site-collapse-custom-collapse .site-collapse-custom-panel {
  background: #f7f7f7;
  border-radius: 2px;
  margin-bottom: 24px;
  border: 0px;
  overflow: hidden;
}

隐藏箭头

你可以通过 showArrow={false} 隐藏 CollapsePanel 组件的箭头图标。

import { Collapse } from 'antd';
const { Panel } = Collapse;
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 with arrow icon" key="1">
      <p>{text}</p>
    </Panel>
    <Panel showArrow={false} header="This is panel header with no arrow icon" key="2">
      <p>{text}</p>
    </Panel>
  </Collapse>,
  mountNode,
);

额外节点

可以同时展开多个面板，这个例子默认展开了第一个。

import { Collapse, Select } from 'antd';
import { SettingOutlined } from '@ant-design/icons';
const { Panel } = Collapse;
const { Option } = Select;
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.
`;
const genExtra = () => (
  <SettingOutlined
    onClick={event => {
      // If you don't want click extra trigger collapse, you can prevent this:
      event.stopPropagation();
    }}
  />
);
class Demo extends React.Component {
  state = {
    expandIconPosition: 'left',
  };
  onPositionChange = expandIconPosition => {
    this.setState({ expandIconPosition });
  };
  render() {
    const { expandIconPosition } = this.state;
    return (
      <div>
        <Collapse
          defaultActiveKey={['1']}
          onChange={callback}
          expandIconPosition={expandIconPosition}
        >
          <Panel header="This is panel header 1" key="1" extra={genExtra()}>
            <div>{text}</div>
          </Panel>
          <Panel header="This is panel header 2" key="2" extra={genExtra()}>
            <div>{text}</div>
          </Panel>
          <Panel header="This is panel header 3" key="3" extra={genExtra()}>
            <div>{text}</div>
          </Panel>
        </Collapse>
        <br />
        <span>Expand Icon Position: </span>
        <Select value={expandIconPosition} onChange={this.onPositionChange}>
          <Option value="left">left</Option>
          <Option value="right">right</Option>
        </Select>
      </div>
    );
  }
}
ReactDOM.render(<Demo />, mountNode);
