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 '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,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,
);
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,
);
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;
}
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,
);
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);
