使用 element-plus 组件库。

    <!-- 左侧菜单 -->
    <div class="layout_slider">
      <Logo></Logo>
      <!-- 展示菜单 -->
      <!-- 滚动组件 -->
      <el-scrollbar class="scrollbar">
        <!-- 菜单组件 -->
        <el-menu :collapse="LayoutSettingStore.fold ? true : false" :default-active="$route.path" background-color="rgb(18 18 18)" text-color="white">
          <!-- 根据路由动态生成菜单 -->
          <Menu  :menuList="userStore.menuRoutes"></Menu>
        </el-menu>
      </el-scrollbar>
    </div>
