        return ArrayHelper::map($result, 'id', 'name');
    }

2、在controller中添加以下action

    public function actions()
    {
        $actions=parent::actions();
        $actions['get-region']=[
            'class'=>\prodcd\region\RegionAction::className(),
            'model'=>\app\models\Region::className()
        ];
        return $actions;
    }

echo $form->field($model, 'province')->widget(\prodcd\region\Region::className(),[
    'model'=>$model,
    'url'=>$url,
    'province'=>[
        'attribute'=>'province',
        'items'=>Region::getRegion(),
        'options'=>['class'=>'form-control form-control-inline','prompt'=>'选择省份']
    ],
    'city'=>[
        'attribute'=>'city',
        'items'=>Region::getRegion($model['province']),
        'options'=>['class'=>'form-control form-control-inline','prompt'=>'选择城市']
    ],
    'district'=>[
        'attribute'=>'district',
        'items'=>Region::getRegion($model['city']),
        'options'=>['class'=>'form-control form-control-inline','prompt'=>'选择县/区']
