1.新建菜单组件NavMenu.vue，从element-plus官网复制一个菜单模板如下：

<template>
  <el-radio-group v-model="isCollapse" style="margin-bottom: 20px">
    <el-radio-button :label="false">expand</el-radio-button>
    <el-radio-button :label="true">collapse</el-radio-button>
  </el-radio-group>
  <el-menu
    default-active="2"
    class="el-menu-vertical-demo"
    :collapse="isCollapse"
    @open="handleOpen"
    @close="handleClose"
  >
    <el-sub-menu index="1">
      <template #title>
        <el-icon><location /></el-icon>
        <span>Navigator One</span>
      </template>
      <el-menu-item-group>
        <template #title><span>Group One</span></template>
        <el-menu-item index="1-1">item one</el-menu-item>
        <el-menu-item index="1-2">item two</el-menu-item>
      </el-menu-item-group>
      <el-menu-item-group title="Group Two">
        <el-menu-item index="1-3">item three</el-menu-item>
      </el-menu-item-group>
      <el-sub-menu index="1-4">
        <template #title><span>item four</span></template>
        <el-menu-item index="1-4-1">item one</el-menu-item>
      </el-sub-menu>
    </el-sub-menu>
    <el-menu-item index="2">
      <el-icon><icon-menu /></el-icon>
      <template #title>Navigator Two</template>
    </el-menu-item>
    <el-menu-item index="3" disabled>
      <el-icon><document /></el-icon>
      <template #title>Navigator Three</template>
    </el-menu-item>
    <el-menu-item index="4">
      <el-icon><setting /></el-icon>
      <template #title>Navigator Four</template>
    </el-menu-item>
  </el-menu>
</template>

<script lang="ts" setup>
import { ref } from 'vue'
import {
  Document,
  Menu as IconMenu,
  Location,
  Setting,
} from '@element-plus/icons-vue'

const isCollapse = ref(true)
const handleOpen = (key: string, keyPath: string[]) => {
  console.log(key, keyPath)
}
const handleClose = (key: string, keyPath: string[]) => {
  console.log(key, keyPath)
}
</script>

<style>
.el-menu-vertical-demo:not(.el-menu--collapse) {
  width: 200px;
  min-height: 400px;
}
</style>

2.新建导航组件NavHeader.vue，从element-plus官网复制一份模板如下：

<template>
  <el-menu
    :default-active="activeIndex"
    class="el-menu-demo"
    mode="horizontal"
    :ellipsis="false"
    @select="handleSelect"
  >
    <el-menu-item index="0">LOGO</el-menu-item>
    <div class="flex-grow" />
    <el-menu-item index="1">Processing Center</el-menu-item>
    <el-sub-menu index="2">
      <template #title>Workspace</template>
      <el-menu-item index="2-1">item one</el-menu-item>
      <el-menu-item index="2-2">item two</el-menu-item>
      <el-menu-item index="2-3">item three</el-menu-item>
      <el-sub-menu index="2-4">
        <template #title>item four</template>
        <el-menu-item index="2-4-1">item one</el-menu-item>
        <el-menu-item index="2-4-2">item two</el-menu-item>
        <el-menu-item index="2-4-3">item three</el-menu-item>
      </el-sub-menu>
    </el-sub-menu>
  </el-menu>
</template>

<script lang="ts" setup>
import { ref } from 'vue'

const activeIndex = ref('1')
const handleSelect = (key: string, keyPath: string[]) => {
  console.log(key, keyPath)
}
</script>

<style>
.flex-grow {
  flex-grow: 1;
}
</style>

3.新建Tab组件NavTab.vue，从vue.draggable的github上复制了一份模板，改造成setup语法糖版本，文档连接如下：vue.draggable中文文档 - itxst.comVue.Draggable是一款基于Sortable.js实现的vue拖拽插件。支持移动设备、拖拽和选择文本、智能滚动，可以在不同列表间拖拽、不依赖jQuery为基础、vue 2过渡动画兼容、支持撤销操作，总之是一款非常优秀的vue拖拽组件。https://www.itxst.com/vue-draggable/tutorial.html

<template>
    <div>
        <draggable class="wrapper" v-model="state.list" @start="state.drag = true" @end="state.drag = false" item-key="index">
            <template #item="{ element }">
                <div class="item">
                    <el-button type="primary">{{ element }}</el-button>
                </div>
            </template>
        </draggable>
    </div>
</template>
  
<script setup>
import { reactive } from 'vue'
import draggable from 'vuedraggable'


const state = reactive({
    drag: false,
    list: [1, 2, 3, 4, 5, 6]
})


</script>
  
<style scoped>
/* 弹性盒子居左对其 */
.wrapper {
    display: flex;
    justify-content: start;
}
/* 间隔10px */
.item {
    margin-left: 10px;
}
</style>

4.views文件夹下新建home文件夹，再新建一个Home.vue组件，内容如下：

<script setup lang='ts'>

</script>

<template>
    <div>
        欢迎回来！
    </div>
</template>

<style lang='less' scoped>
</style>

5.将各个功能组件，放到布局组件中：修改LayoutMain.vue如下：

<script setup>
 import NavMenuVue from './NavMenu.vue';
 import NavHeaderVue from './NavHeader.vue';
 import NavTabVue from './NavTab.vue';
 import HomeVue from '../../views/home/Home.vue';
</script>
 
<template>
    <!-- 容器 -->
    <div class="root-container">
        <!-- 左半边 -->
        <div class="left">
            <!-- LOGO区 -->
            <div class="left-logo"></div>
            <!-- 菜单区 -->
            <div class="left-menu">
                <NavMenuVue></NavMenuVue>
            </div>
        </div>
        <!-- 右半边 -->
        <div class="right">
            <!-- 页头区 -->
            <div class="right-header">
                <NavHeaderVue></NavHeaderVue>
            </div>
            <!-- Tab区 -->
            <div class="right-tab">
                <NavTabVue></NavTabVue>
            </div>
            <!-- 主显示区 -->
            <div class="right-main">
                <component :is="HomeVue"></component>
            </div>
        </div>
    </div>
</template>
 
<style lang="less" scoped>
/* 容器满屏 */
.root-container {
    background-color: white;
    height: 100%;
    width: 100%;
    // 弹性盒子模型
    display: flex;
    // 盒子左右排列
    flex-direction: row;
    // 水平对齐
    justify-content: start;
    // 垂直对齐
    align-items: center;
}
 
.left {
    background-color: gray;
    width: 200px;
    height: 100%;
 
    .left-logo {
        background-color: #6d6b6b;
        width: 100%;
        height: 85px;
    }
 
    .left-menu {
        width: 100%;
        height: calc(100% - 85px);
    }
}
 
.right {
    background-color: rgb(209, 205, 205);
    // 使用计算占满剩余宽度
    width: calc(100% - 200px);
    height: 100%;
 
    .right-header {
        background-color: #f5f4f4;
        width: 100%;
        height: 58px;
    }
 
    .right-tab {
        background-color: #e0dcdc;
        width: 100%;
        height: 35px;
    }
 
    .right-main {
        background-color: white;
        width: 100%;
        // 使用计算占满剩余高度
        height: calc(100% - 58px - 35px);
    }
}
</style>
