效果图：
这个布局用到了以下组件：
1.v-navigation-drawer侧边栏
- rail：用来控制侧边栏折叠和展开状态，等于false，是展开状态，否则折叠状态。
- permanent：等于true的时候，无论屏幕大小如何变化，侧边栏始终处于展开状态。

import IconDashboard from "~icons/mdi/view-dashboard"
import IconAbout from "~icons/mdi/information"
/*--------------------------------------------------------*///rail=false表示打开状态，侧边栏一开始就是打开状态
const sideBarOpen = ref(false)emitter.on('toggleSideBar', (value) => {sideBarOpen.value = value
})
