给主键的li 和a标签添加元素
$this->myMenu = array(

'id'=>'myMenu',

'items'=>array(

	array(

		'label'=>'Home',

		'url'=>array('site/index'),

		'itemOptions'=>array('class'=>'visited'),

		'linkOptions'=>array('class'=>'bar'),

	),

	array('label'=>'Sign Out', 'url'=>array('site/signout')),

),

);
给ul添加元素

$this->widget('zii.widgets.CMenu', array(

	'id'=>'myMenu',

	'items'=>$this->myMenu,

	'htmlOptions'=>array('class'=>'span-24 last'),

));

this will make Yii render

<ul class="span-24 last" id="myMenu">

...

</ul>
