yiibooster select2group tags to model (database)

in booster widget tbActiveform, i will add select2group widget, with multiple selected, so i use "tags" attribute,

	<div class="row">

		<?= $form->select2Group($model,'zat_aktif',[

				'wrapperHtmlOptions'=>[

					'class'=>'col-sm-5',

				],

				'widgetOptions'=>[

					'asDropDownList' => false,

					'options'=>[

					'placeholder'=>'Select Metode',

					'tokenSeparators' => [',', ' '],

			//		'tags' => array('clever', 'is', 'better', 'clevertech'),
