vue-element-admin点击进入详情页，侧边栏高亮问题

只需要在meta里面添加activeMenu

 {
    path: '/example',
    component: Layout,
    redirect: '/example/list',
    name: 'Example',
    meta: {
      title: 'Example',
      icon: 'el-icon-s-help'
    },
    children: [
      {
        path: 'details',
        component: () => import('@/views/example/edit'),
        name: 'EditArticle',
        meta: { title: 'Edit Article', noCache: true, activeMenu: '/example/list' },
        hidden: true
      }
     ]
  }
