yii2 gridView中使用下拉列表筛选数据

view:

'columns' => [
  ['class' => 'yii\grid\SerialColumn'],
  'id',
  [
    'attribute' => 'category_id',
    'label'=>'类型',
    'value'=>
      function($model){
        return  $model->getCategoryName();   //
      },
      'filter' => $model->getCategoryList(),     //筛选的数据
    ],
]

model:

    /**
     * 分类列表
     * @return array
     */
    public function getCategoryList(){
        $result = [];
        $list = Category::find()->where(["status" => Category::STATUS_NORMAL])->asArray()->all();
        if(!empty($list)){
            $result = ArrayHelper::map($list,"id","category_name");
        }
        return $result;
    }

    /**
     * 关联分类表
     * @return \yii\db\ActiveQuery
     */
    public function getCategory(){
        return $this->hasOne(Category::className(),["id" => "category_id"]);
    }

    /**
     * 分类名称
     * @return string
     */
    public function getCategoryName(){
        return empty($this->Category)?"":$this->Category->category_name;
    }

效果:
