Css class in menu widget

Yii 2.0 General Discussions

When using the menu widget, how can I have a class applied to both “ul” and “li” elements? I’m able to set the “li” class with the “options” property but I can’t find a way to set the “ul” class. I’ve tried with “itemOptions”, “firstItemCssClass”, “lasstItemCssClass”, but without success.




<?php		

'label' => '<i class="fa fa-laptop"></i> <span>Products</span><i class="fa fa-angle-left pull-right"></i>', 'url' => ['product/index'],

	'options' => ['class' => 'treeview'],

	//'itemOptions' => ['class' => 'treeview-menu'],  

	'items' =>[

	['label' => '<i class="fa fa-desktop"></i> <span>Desktop</span>', 'url' => ['desktop/index']],

	['label' => '<i class="fa fa-laptop"></i> <span>laptop</span>', 'url' => ['laptop/index']],

	],

	],						




	Now this is the ouptput I get. What's missing is th &quot;ul&quot; class:




<html>

<li class="treeview">

   <a href="/yii2/backend/product/index">

	<i class="fa fa-laptop"></i>

		<span>Products</span>

	<i class="fa fa-angle-left pull-right"></i>

   </a>

   <ul> ---> I want the class here <ul class="treeview-menu">

		<li>...

		<li>...

</ul>

</li>

Thank you!
