根據(jù)laravel的基本操作步驟依次完成如下操作：
主要是參考laravel-admin內(nèi)置的Menu菜單管理的功能，利用ModelTree實(shí)現(xiàn)業(yè)務(wù)中的Tree數(shù)據(jù)管理。

1. 創(chuàng)建模型
    php artisan make:model Models/Category
2. 創(chuàng)建遷移文件
    php artisan make:migration create_categories_table
3. 創(chuàng)建填充文件
    php artisan make:seeder CategoriesSeeder
4. 創(chuàng)建后端控制器
    php artisan admin:make CategoryController --model=AppModelsCategory
5. 創(chuàng)建后端路由
    app/admin/routes.php ： $router->resource("/web/categories",CategoryController::class);
6. 添加后端菜單
    /web/categories：菜單路徑
7. 其他定義及編輯定制
