Collapse 折叠面板

可以折叠/展开的内容区域。

何时使用

对复杂区域进行分组和隐藏，保持页面的整洁。
手风琴 是一种特殊的折叠面板，只允许单个内容区域展开。

代码演示

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 'choerodon-ui';
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);

手风琴

手风琴，每次只打开一个tab。默认打开第一个。

import { Collapse } from 'choerodon-ui';
const Panel = Collapse.Panel;

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 'choerodon-ui';
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}>
    <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 'choerodon-ui';
const Panel = Collapse.Panel;

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、圆角和边距。

import { Collapse } from 'choerodon-ui';
const Panel = Collapse.Panel;

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 customPanelStyle = {
  background: '#f7f7f7',
  borderRadius: 4,
  marginBottom: 24,
  border: 0,
  overflow: 'hidden',
};

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

隐藏箭头

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

import { Collapse } from 'choerodon-ui';
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 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);
