vue3.0+element Plus实现页面布局侧边栏菜单路由跳转功能

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [

        ],
      },
      component: () => import("../views/project/Index.vue"),
      children: [
        {
          path: "sample/:id",
          name: "projectGroup:sample",
          meta: {
