vue-element-admin路由不在侧边栏显示，路由不在面包屑导航显示

比如：列表页想显示在左侧菜单，添加和编辑路由，不想显示在左侧菜单和面包屑导航

代码：

{
    path: '/about',
    component: Layout,
    redirect: '/about/list',
    name: '单页管理',
    meta: {
      title: '单页管理',
      icon: 'el-icon-s-help'
    },
    children: [
      {
        path: '/about/cat',
        component: () => import('@/views/about/cat'),
        name: 'AboutCat',
        meta: { title: '单页分类', icon: 'tree' }
      },
      {
        path: 'list',
        component: () => import('@/views/about/list'),
        name: 'AboutList',
        meta: { title: '单页列表', icon: 'list' }
      },
      {
        path: 'edit',
        component: () => import('@/views/about/edit'),
        name: 'EditList',
        hidden: true, // 该路由不会在侧边栏显示
        meta: { breadcrumb: false }, // 该路由不会在面包屑导航显示
      },
    ]
  },
