There is an example how to create CTreeView

private function generateTree($models)
{
    $data = array();

    foreach ($models as $category) {
        $data[$category->id] = array(
            'id'   => $category->id,
            'text' => '<a href="/admin/catalog/category/id/'.$category->id.'">'.$category->category_name.'</a>',

        );
        foreach ($category->goods as $item) {
            $data[$category->id]['children'][$item->id] = array(
                'id'   => $item->id,
                'text' =>  '<a href="/admin/catalog/item/id/'.$item->id.'">'.$item->article.'</a>',
                'expanded' => false,
            );
        }

    }
    return $data;
}

In view

$this->widget('CTreeView', array('data' => $data,'persist'=>'cookie'));
