临时菜单是啥意思，请问大家遇到过么

开发插件，参考dvadmin-pay。但dvadmin-pay初始化之后也是看不见菜单的，我不知道是哪里控制了，只能看见目录。

[

{
    "name": "订单管理",
    "icon": "cubes",
    "sort": 0,
    "is_link": false,
    "is_catalog": true,
    "web_path": "",
    "component": "",
    "component_name": null,
    "status": true,
    "cache": false,
    "visible": true,
    "parent": null,
    "children": [
        {
            "name": "统计图表",
            "icon": "area-chart",
            "sort": 0,
            "is_link": false,
            "is_catalog": false,
            "web_path": "/charts",
            "component": "tenantManage/order/index",
            "component_name": null,
            "status": true,
            "cache": false,
            "visible": true,
            "children": [],
            "menu_button": []
        },
        {
            "name": "订单列表",
            "icon": "fa fa-list-alt",
            "sort": 1,
            "is_link": false,
            "is_catalog": false,
            "web_path": "/orderList",
            "component": "tenantManage/order/index",
            "component_name": null,
            "status": true,
            "cache": false,
            "visible": true,
            "children": [],
            "menu_button": []
        }
    ],
    "menu_button": []
}

]

必须有component,子菜单才会被显示

临时菜单应该是指没有可用的子菜单
