Pull down the search, let’s take a look at the expected renderings first

How to achieve it specifically? Considering that a data table may have many fields that require drop-down effects, we first implement a method in its model to facilitate subsequent operations

/**
 *  下拉筛选
 *  @column string 字段
 *  @value mix 字段对应的值，不指定则返回字段数组
 *  @return mix 返回某个值或者数组
 */
public static function dropDown ($column, $value = null)
{
    $dropDownList = [
        'is_delete'=> [
            '0'=>'显示',
            '1'=>'删除',
        ],
        'is_hot'=> [
            '0'=>'否',
            '1'=>'是',
        ],
        //有新的字段要实现下拉规则，可像上面这样进行添加
        // ......
    ];
    //根据具体值显示对应的值
    if ($value !== null) 
        return array_key_exists($column, $dropDownList) ? $dropDownList[$column][$value] : false;
    //返回关联数组，用户下拉的filter实现
    else
        return array_key_exists($column, $dropDownList) ? $dropDownList[$column] : false;
}

Then we go to the code to see how to implement the drop-down search

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        // ......
        [
            'attribute' => 'is_hot',
            'value' => function ($model) {
                return Article::dropDown('is_hot', $model->is_hot);
            },
            'filter' => Article::dropDown('is_hot'),
        ],
        [
            'attribute' => 'is_delete',
            'value' => function ($model) {
                return Article::dropDown('is_delete', $model->is_delete);
            },
            'filter' => Article::dropDown('is_delete'),
        ],
        // ......
    ],
]); ?>

Like this, we Simply implement two drop-down effects. To implement the filtering function, just add the search conditions for this field in your dataProvider.

The above introduces the yii2 GridView drop-down search implementation case tutorial, including GRIDVIEW content. I hope it will be helpful to friends who are interested in PHP tutorials.
