I have a dropdown menu in a row in a portlet.
<div class="col-md-6">
<p class="todo-red todo-inline">Gestionnaire : <span class="bold">Name</span></p>
</div>
<div class="col-md-5">
<span class="bold caption-subject uppercase font-grey-mint">Inactif depuis : 26 J</span>
</div>
<div class="col-md-1">
<div class="btn-group">
<a class="btn btn-sm btn-default todo-add-button" href="javascript:;" data-toggle="dropdown" data-hover="dropdown" data-delay="1000" data-close-others="true" aria-expanded="false"><i class="fas fa-volume-mute" aria-hidden="true"></i></a>
<ul class="dropdown-menu">
<li><a href="javascript:;"><i class="fa fa-pencil" aria-hidden="true"></i> 1 jour </a></li>
<li><a href="javascript:;"><i class="fa fa-pencil" aria-hidden="true"></i> 3 jours </a></li>
<li><a href="javascript:;"><i class="fa fa-pencil" aria-hidden="true"></i> 15 jours </a></li>
<li><a href="javascript:;"><i class="fa fa-pencil" aria-hidden="true"></i> Définitif </a></li>
</ul>
</div>
</div>
It's look like that: dropdown behind the portlet
The dropdown menu is behind the portlet, I need to have it above the portlet. I tried to z-index with position:absolute but nothing work. I haven't find any good help on SO. Have you any ideas about my issue?
Thank you
