关于Yii实现的多级联动下拉菜单

<?php echo CHtml::activeDropDownList($model,'zmg_id',MemGroup::model()->getMemGroup(),array(
    'class'=>'s_ipt w_120',
    'empty'=>'请选择会员组',
    'ajax' =>array(
          'type'=>'GET',
          'url'=>CController::createUrl('cmpTemplates/getMemType'),
          'update'=>'#CmpTemplates_zmg_ids',
          'data'=>array('mid'=>"js:this.value")
          ),
    ))?>
<?php echo $form->dropDownList($model,'zmg_ids',array(),array('class'=>'s_ipt w_120','empty'=>'选择会员等级'))?>
