You can set $var in kartik Depdrop widget, as the same scenario in the Dropdown widget here We use kartik depdrop widget

where(['id' => $model->customer_id])->all(), 'id',
            function ($model) {
                return $model['id'] .' - '. $model['name'];
            });
        echo $form->field($model, 'id')->widget(DepDrop::classname(), [
            'data' => $var,
            'pluginOptions' => [
                'depends' => [''],
                'url' => Url::to(['#'])
            ]
        ]) ?>
