## zh-CN

Layout.Sider 支持响应式布局。

> 说明：配置 `breakpoint` 属性即生效，视窗宽度小于 `breakpoint` 时 Sider 缩小为 `collapsedWidth` 宽度，若将 `collapsedWidth` 设置为零，会出现特殊 trigger。

## en-US

Layout.Sider supports responsive layout.

> Note: You can get a responsive layout by setting `breakpoint`, the Sider will collapse to the width of `collapsedWidth` when window width is below the `breakpoint`. And a special trigger will appear if the `collapsedWidth` is set to `0`.

```jsx
import { Layout, Menu } from 'antd';
import { UploadOutlined, UserOutlined, VideoCameraOutlined } from '@ant-design/icons';

const { Header, Content, Footer, Sider } = Layout;

ReactDOM.render(
  <Layout>
    <Sider
      breakpoint="lg"
      collapsedWidth="0"
      onBreakpoint={broken => {
        console.log(broken);
      }}
      onCollapse={(collapsed, type) => {
        console.log(collapsed, type);
      }}
    >
      <div className="logo" />
      <Menu theme="dark" mode="inline" defaultSelectedKeys={['4']}>
        <Menu.Item key="1" icon={<UserOutlined />}>
