setAttributes method of KnpMenuBundle doesn't work

I'm using KnpMenuBundle in my Symfony2 application.
I'm trying to set the menu class attribute using setAttributes of FactoryInterface of KnpMenuBundle like this: 

    $menu = $factory->createItem('root');
    $menu->setAttribute('class' , 'sf-menu');

But this doesn't work! and the resulting markup with or without the setAttribute line is: 

<ul>
    <li class="first">
     ...
</ul>

while I expect to have <ul class='sf-menu'>

What is the problem?

Solution

  • If you want to give a class to li elements, you have to set it this way:

    $menu->addChild('Label', [
    ...
    'attributes' => ['class' => 'sf-menu'],
]);

    If you want to give a class to your ul element:

    $menu = $this->factory->createItem('root');
$menu->setChildrenAttribute('class', 'sf-menu');
