Yii Nested Set To Dropdown Menu

Yii 1.1 General Discussion

I’m using Yii nested set behavior, which helps me to keep my categories nested as seen here (nevermind title rows, they are in russian):

And all I want to do is to have Bootstrap nested menu, which should be like this:


    

    $criteria = new CDbCriteria;

    $criteria->order = 'root, lft';

    $categories = Category::model()->findAll($criteria);

    foreach($categories as $i => $category) {

      $items[$i]['label'] = $category->title;

      $items[$i]['url'] = $category->url;

      $items[$i]['active'] = false;

      $items[$i]['items'] = array(

        array('label'=>'123', 'url'=>'#'),

        array('label'=>'123', 'url'=>'#'),

        array('label'=>'123', 'url'=>'#', 'items'=>array(

            array('label'=>'1234', 'url'=>'#'),

            array('label'=>'1234', 'url'=>'#'),

            array('label'=>'1234', 'url'=>'#', 'items'=>array(

                array('label'=>'1234', 'url'=>'#'),

                array('label'=>'1234', 'url'=>'#'),

                array('label'=>'1234', 'url'=>'#'),

            )),

        )),

    ); 

}

$this->widget('bootstrap.widgets.TbMenu', array(

    'type'=>'pills',

    'stacked'=>false, // whether this is a stacked menu

    'items'=>$items

));

I don’t understand how to get this done, btw I read this topic and just don’t know how actually apply this function to my problem.

Appreciate any help.
