echo $form->field($model, 'column_name')->widget(Select2::classname(), [
'data' => ['test-1'=>'Test-1','test-2'=>'Test-2','test 3'=>'Test-3','test@1'=>'Test @ 4'],
'language' => 'en',
'options' => [
'placeholder' => 'Search Data ',
],
'pluginOptions' => [
'allowClear' => true,
'multiple' => true,
],
]);
