knp menu bundle - how to add tags to a tag?

Question

How to add tags to (a) tag ? I can add to a ->setLinkAttribute('class', 'fa fa-edit') but this does not solve my problem. If I add ->setLabel('<i class="fa fa-edit"></i>Forms') It show my tags element as well. I would like to achieve like below:

<ul>
     <li>
      <a>
        <i class="fa fa-edit"></i>  <--here
        Forms
        <span class="fa fa-chevron-down"></span> <--here
      </a>
    </li>
</ul>

Answer 1

I found a solustion.

I changed:

{{ knp_menu_render('InfAccountBundle:Builder:Menu') }}

to:

{{ knp_menu_render('InfAccountBundle:Builder:Menu', {'allow_safe_labels': true}) | raw }}

and added extra to label:

$menu->addChild('Baza', array('uri' => '#','childrenAttributes' => array(
                'class' => 'nav child_menu',
            )))->setLabel('<i class="fa fa-edit"></i>Baza<span class="fa fa-chevron-down"></span>')->setExtra('safe_label',true);
