vue element 多级菜单 嵌套路由跳转问题

1.在二级菜单加一个<router-view></router-view>标签 (用来承载三级菜单页面)

2.在项目路由中的meta标签加一个参数开关来控制是否隐藏二级菜单页面

　　

 

  {
    path: '/structure',
    component: Layout,
    // redirect: '/permission/page',
    alwaysShow: true, // will always show the root menu
    name: 'Permission',
    meta: {
      title: 'structure',
      icon: 'blockchain',
      roles: ['admin'] // you can set roles in root nav
    },
    children: [
      // 1级页面 构建列表页
      {
        path: 'index',
        component: () => import('@/views/baas/chain'),
        name: 'Blockchain',
        meta: {
          title: 'blockchain',
          showRole: true
        },
        children: [
          //2级页面 链详情页 通道
