如何在Laravel中获取多级动态下拉菜单

Question

我正在插入动态菜单，但是在获取动态下拉菜单时遇到问题。

当我单击子菜单时，它将重定向到该子菜单页面，但是从那里将不会重定向到第三级菜单，当我单击索引中的第三级菜单并且无法从第三级访问第二级菜单时，会出现相同的问题菜单页面。

控制器：

    public function subcategory($subcat_name)
    {

        $flag = false;
        $menus               =  Categorymodel::get();
        $submenus            =  SubmenuModel::get();
        $third_levelmenus    =  SubcategoryModel::get();

        $viewSubcategory=DB::table('subcategory')->select('cat_id','subcat_name','subcat_description')->where('subcat_name',$subcat_name)->get();

        foreach($viewSubcategory as $viewSubcategorys)
        {
            $cat_id=$viewSubcategorys->cat_id;
        }
        $viewcategory=DB::table('category')->select('category_name')->where('id',$cat_id)->get();
        return view('subcategory',compact('menus','submenus','third_levelmenus'),['viewSubcategory' => $viewSubcategory,'viewcategory' =>$viewcategory,'flag' => $flag]);
    }

     public function thirdLevelMenus($subcategory_cat)
     {
        $flag = false;
        $menus               =  Categorymodel::get();
        $submenus            =  SubmenuModel::get();
        $third_levelmenus    =  SubcategoryModel::get();

        $thirdLevelMenu=DB::table('subcategory_cat')->select('subcat_id','category_name','subcategory_description','subcategory_cat')->where('subcategory_cat',$subcategory_cat)->get();

        foreach($thirdLevelMenu as $thirdLevelMenus)
        {
            $subcat_id=$thirdLevelMenus->subcat_id;
        }
        $viewsubcategories=DB::table('subcategory')->select('subcat_name','cat_id')->where('id',$subcat_id)->get();
        foreach($viewsubcategories as $viewsubcategorie)
        {
            $cat_id=$viewsubcategorie->cat_id;
        }
        $viewcategories=DB::table('category')->select('category_name')->where('id',$cat_id)->get();
        return view('third-level-menus',compact('menus','submenus','third_levelmenus'),['thirdLevelMenu' => $thirdLevelMenu,'viewsubcategories' =>$viewsubcategories,'viewcategories'=>$viewcategories,'flag' => $flag]);
     }

查看：

 @if($flag)
     @foreach($menus as $menu)
     @if($menu->status==1)
         <li class="nav-item dropdown">
             <a class="nav-link abouts" href="#" id="{{$menu->id}}">{{ $menu->category_name }}</a>

             @if(!$submenus->isEmpty())
