Animate.css trouble with z-index - html

Question

I'm using the animate.css framework to handle cool animations for the web application I'm building, but I'm having z-index issues when it comes to displaying my content. (I should also note that I'm using the Twitter Bootstrap framework as well.)
As an example, if I have a menu, and then a panel that displays right below it, the drop downs of the menu will be displayed behind the panel, when in reality, I want them to display in front. Here is a basic JSFiddle example of the problem I'm having.
Here is the HTML of that example.
<div class="container">
<div class="animated fadeInLeft">
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>Home</li>
<li class="dropdown">
Drop Down 1<span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li>Element 1</li>
<li>Element 2</li>
</ul>
</li>
<li class="dropdown">
Drop Down 2 <span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li>Element 1</li>
<li>Element 2</li>
</ul>
</li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
</div>
<div class="animated fadeInLeft">
<div class="panel panel-primary">
<div class="panel panel-header">
My Panel
</div>
</div>
</div>
I'm applying the "animated" class to both the panel and menu separately (on purpose because in my application, the menu will be loaded in once, while a different panel could be loaded in), but when I remove the class from one of them, it works perfectly. In other words, if ONLY one of the elements have the "animated" class, it works. If they both have the "animated" class, it doesn't.
Does anyone have an idea on how I could fix this?
Thanks.

Answer 1

Remove the unnecessary divs and attach the animation classes directly to the elements themselves. Then you can set the z-index as desired.
I suspect your problem may have been caused by the opacity change in the animation, but I'm not too sure about that.
Working Example
.panel {
z-index: 1
}
nav {
z-index:2
}
<div class="container">
