Here I added the code for CListview of yii. Using this we can assign the parent tag name and class of parent tag to CListview.
<?php
$this->widget('zii.widgets.CListView', array(
'id'=>'commentslistview',
/** tag name **/
'itemsTagName'=>'ul',
/** calss name **/
'itemsCssClass'=>'commentslist',
'dataProvider'=>$commentsProvider,
'itemView'=>'_comments',
));
?>
