效果图：

 

 这个布局用到了以下组件：

1.v-navigation-drawer侧边栏

1. 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。
2. 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。

<script setup>
import { ref } from "vue"
import emitter from "@/utils/emitter.js"/*---------------------------导入icon图标------------------*/
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
})

</template>

2.v-app-bar头部导航

<script setup>
import emitter from "@/utils/emitter.js"
import { ref } from "vue"/*--------------------------导入icon----------------*/
import IconClose from "~icons/mdi/menu-close"
import IconOpen from "~icons/mdi/menu-open"
/*-------------------------------------------------*/const sideBarOpen = ref(false)const toggleSideBar = () => {sideBarOpen.value = !sideBarOpen.valueemitter.emit('toggleSideBar', sideBarOpen.value)
}
</script><template><v-app-bar><template v-slot:prepend><component:is="sideBarOpen ? IconClose : IconOpen"@click="toggleSideBar"class="cursor-pointer text-h6 ml-2"></component></template></v-app-bar>
</template>
