hi all . how to create submenu for below code:
$this->widget('bootstrap.widgets.TbButtonGroup', array(
'type' => 'primary', // '', 'primary', 'info', 'success', 'warning', 'danger' or 'inverse'
'buttons' => array(
array('label' => 'Action', 'url' => '#'), // this makes it split <img src='http://www.yiiframework.com/forum/public/style_emoticons/default/smile.gif' class='bbc_emoticon' alt=':)' />
array('items' => array(
array('label' => 'Action', 'url' => '#'),
array('label' => 'Another action', 'url' => '#'),
array('label' => 'Something else', 'url' => '#'),
array('label' => 'Separate link', 'url' => '#'),
