Yii Rights set sub menu visible false based on Role

Question

I am new to Yii Framework. In my application iam used Rights using this link : http://www.yiiframework.com/wiki/423/installing-yii-users-and-rights-to-newly-created-yii-app/

I want to make navigation bar submenu item visible based on user's role in yii rights.

my navigation sub menu item looks like this :

array(
    'label'=>'Low Inventory Level <span class="caret"></span>',
    'url'=>'#',
    'itemOptions'=>array('class'=>'dropdown','tabindex'=>"-1"),
    'linkOptions'=>array('class'=>'dropdown-oggle','data-toggle'=>"dropdown"),
    'items'=>array(
        array('label'=>'RM Warehouse', 'url'=>array('/rmlInventoryMwh/load')),
        array('label'=>'Prod Warehouse', 'url'=>array('/rmlInventoryPwh/load ')),
    ),
    'visible' => Yii::app()->user->checkAccess('master'),
)

Answer 1

Just add checkAccess to your sub menu:

    array(
    'label'=>'Low Inventory Level <span class="caret"></span>',
    'url'=>'#',
    'itemOptions'=>array('class'=>'dropdown','tabindex'=>"-1"),
    'linkOptions'=>array('class'=>'dropdown-oggle','data-toggle'=>"dropdown"),
    'items'=>array(
        array('label'=>'RM Warehouse', 'url'=>array('/rmlInventoryMwh/load'),'visible' => Yii::app()->user->checkAccess('sub_menu')),
        array('label'=>'Prod Warehouse', 'url'=>array('/rmlInventoryPwh/load '),'visible' => Yii::app()->user->checkAccess('sub_menu')),
    ),
    'visible' => Yii::app()->user->checkAccess('master'),
)

And then just add permissions to your operation for user roles.
