Answer

first of all install any datepicker widget i.e 2amigos date picker

use dosamigosdatepickerDatePicker;

in your index grid

    <?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
    'columns' => [
    'id',
        'packageId',
        'all_amount',
        'title',
    [
                    'attribute'=>'attribute_name',
                    'value' =>'attribute_name',

                    'filter'=>DatePicker::widget([
            'model' => $searchModel,
            'attribute'=>'attribute_name',
                'clientOptions' => [
                    'autoclose' => true,
                    'format' => 'yyyy=M-dd'
                ]
        ])       
],
    ],
        ]); 

        ?>

In your controller in actionindex()

public function actionIndex()
    {
        $searchModel = new <model name>Search();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

        return $this->render('index', [
            'searchModel' => $searchModel,
            'dataProvider' => $dataProvider,
        ]);
    }
