php - Add Class to knp menu root Element with Twig -

what right way add together class knp_menu's root element <ul> twig?

i tried lot of things:

1.

{{ knp_menu_render('main', {'class': 'foo'}) }}

2.

{{ knp_menu_render('main', {'attributes': {'class': 'foo'}}) }}

3.

{{ knp_menu_render('main', {'listattributes': {'class': 'foo'}}) }}

4.

{{ knp_menu_render('main', {'attributes': {'listattributes': {'class': 'foo'}}}) }}

none of them worked

you can add together in menu builder like..

$menu = $this->factory->createitem('root', array( 'childrenattributes' => array( 'class' => 'foo', ), ));

update

i got notification , found way although requires utilize custom template accomplish it.

in client template need override list block like..

{% block list %} {% if item.haschildren , options.depth not sameas(0) , item.displaychildren %} {% import _self knp_menu %} <ul{{ knp_menu.attributes(listattributes|merge({'class': [ options.rootclass defined ? options.rootclass : '', listattributes.class defined ? listattributes.class : '' ]|join(' ') })) }}> {% set options = options|merge({'rootclass': '' }) %} {{ block('children') }} </ul> {% endif %} {% endblock %}

in rather utilize knp_menu.attributes(listattributes) pass in array on-the-fly generated listattributes.class value. attribute generate joining option.rootclass (if exists) listattributes.class (if exists) listattributes.class value.

the option.rootclass value reset '' after utilize using {% set options = options|merge({'rootclass': '' }) %} not added every sub-menu.

this allow render menu using..

{{ knp_menu_render('main', {'rootclass': 'foo' }) }}
