## 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`.
