yii2 - kartik DynaGrid select2过滤器不渲染

Question

我的设置专栏使用 kartik DynaGrid Widget 在 yii2 上显示数据。但过滤器（FILTER_SELECT2）不会呈现在我的桌子上。有人能帮我吗？请。

    'class' => 'kartik\grid\DataColumn',
    'attribute' => 'city_id',
    'label' => 'City',
    'hAlign' => 'center',
    'vAlign' => 'middle',
    'width' => '70px',
    'filterType' => GridView::FILTER_SELECT2,
    'filter' => [
       1 => 'filter 1',
       2 => 'filter 2',
    ],
    'format' => 'html',
    'value' => function($data){
        $cities = \app\models\City::getData();
        if(isset($cities[$data->city_id])){
            return $cities[$data->city_id];
        }

        return $data->city_id;

    }

发布您的网格配置。也许你在配置中关闭了过滤器。默认配置是这样的

 ....
    'gridOptions'=>[
            'dataProvider'=>$dataProvider,
            'filterModel'=>$searchModel,
            ....
    ],
