Right Justify Zii.widgets.cmenu Item

How Do I align zii.widgets.CMenu items to the right side instead of the left?

Currently, within my protected/views/layouts/main.php I have the following code that aligns the item Logout to the left. But I want to align this to the right. How Do I do this?

	<div id="mainmenu">

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


			    array('label'=>'Logout ('.Yii::app()->user->name.')', 'url'=>array('/site/logout'), 'visible'=>!Yii::app()->user->isGuest)


		)); ?>

	</div><!-- mainmenu -->

<div id="mainmenu" style="text-align:right;">
