To add a CheckboxColumn to the  yii\grid\GridView , add it to the  columns  configuration as follows: 'columns'  => [      // ...      [          'class'  =>  'yii\grid\CheckboxColumn' ,          // you may configure additional properties here      ], ] This is the view: <?= Html :: beginForm ([ 'controller/bulk' ], 'post' );?> <?= Html :: dropDownList ( 'action' , '' ,[ '' => 'Mark selected as: ' , 'c' => 'Confirmed' , 'nc' => 'No Confirmed' ],[ 'class' => 'dropdown' ,])?> <?= Html :: submitButton ( 'Send' , [ 'class' => 'btn btn-info' ,]);?> <?= GridView :: widget ([ 'dataProvider' => $dataProvider , 'columns' => [ [ 'class' => 'yii\grid\CheckboxColumn' ], 'id' , ], ]); ?> <?= Html :: endForm ();?> This is
