    @endfor
    </select>
    </div>

and this my web Route file

    Route::get('/', function () {
    return view('welcome');
    });

    Auth::routes();

    Route::get('/home', 'HomeController@index')->name('home');



    Route::get('/manager','ManagerController@dashboard');

    Route::post('/manager','ManagerController@addItem');

    Route::get('/manager/{id}','ManagerController@deleteTable')->name('admin.deleteTable');

    Route::post('/manager','ManagerController@destroyDish')->name('admin.distroyDish');

    Route::post('/manager' ,'ManagerController@addIngrediant')->name('admin.addIngrediant');

    Route::get('/kitchen' , 'KitchenController@index')->name('kitchen.home');

   Route::get('/kitchen/{id}' ,'KitchenController@submitDish')->name('kitchen.submit.dish');

   Route::post('/kitchen','KitchenController@addIngrediant')->name('kitchen.addIngrediant');

and this ManagerController

    private function initData(){
     $InetialData = array(
        'category'=> DB::table('Category')->get(),
        'dish'   => DB::table('Items')->get(),
        'users'   => DB::table('users')->get(),
        'Ingrediant' => DB::table('Ingrediant')->get(),
        'IngrediantHistory' => DB::table('IngrediantHistory')->get()
    );


    return $InetialData;
    }

    public function destroyDish(Request $request){

    DB::table('Items')->where('id', '=',$request->dish)->delete();

    return redirect('/manager')->with('InetialData' , $this->initData());
    }
