# 隐藏侧边栏内容
有时候收起边栏后，你不想看到里面有什么。
```html
<n-switch v-model="collapsed" />
<n-layout style="height: 240px;">
  <n-layout-header style="height: 64px;">
    酷的页头
  </n-layout-header>
  <n-layout>
    <n-layout-sider
      collapse-mode="width"
      :show-content="!collapsed"
      :collapsed-width="120"
      :width="240"
      :collapsed="collapsed"
      show-toggle-button
      @collapse="collapsed = true"
      @expand="collapsed = false"
