Answer 1

$criteria->compare('parent_cat',$this->parent_cat); 

<div class="col-md-3"> 
<?php 
    $Categories = Categories::model()->findAll(); 
    $listData = CHtml::listData($Categories,'id','name'); 
    $listData[0] = "Категория продукта"; 
    ksort($listData); 
    echo $form->dropDownList($model,'parent_cat',$listData, array('class'=>'form- control','options' => array($model->parent_cat=>array('selected'=>true)))); 
?> 
</div>
