vue-element-admin只有1個二級導航時也要展示

問題: 默認情況下,一級導航下面只有1個二級導航的時候, 一級導航會不做顯示, 僅展示二級導航.

需求: 一級導航和二級導航都展示, 如下面右圖

 

 

僅需要在路由寫上這行就行 

alwaysShow: true,

// 全部是這樣
{
    path: "/management",
    component: Layout,
    redirect: "/management/toPayOrder",
    name: "OrderManagement",
    alwaysShow: true, // 就是這行顯隱起作用的
    meta: {
      title: "管理",
      icon: "el-icon-s-grid"
    },
    children: [
      {
        path: "toPayOrder",
        name: "ToPayOrder",
        component: () => import("@/views/management/toPayOrder"),
        meta: {
          title: "財務訂單",
          icon: "el-icon-menu"
        },
        hidden: false
      },
      {
        path: "toPayOrderDetail",
        name: "ToPayOrderDetail",
        component: () =>
          import("@/views/management/detail/orderDetail"),
        meta: {
          title: "詳情"
        },
        hidden: true
      }
    ]
  },
