Twitter Bootstrap Collapsing Menu not in front of other elements - html

Question

I'm using twitter bootstrap 2.3 and when I make my browser smaller it collapses correctly but when I click on the button to do the dropdown it doesn't appear in front of the other items. Here is a working demo: http://www.thehighlightnetwork.com/ I've been trying to fix it in the developer tools in Chrome but to no avail.
Here is the relevant code:
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="brand" href="/"><img src="http://i.imgur.com/8dN9Ck1.png" alt="small logo" style="height:50px;"></a>
<div class="nav-collapse collapse" style="height:0px;">
<ul class="nav">
<li>The Highlight Network</li>
<li>Official Blog</li>
<li>Profile</li>
<li>Logout</li>
<li>Sign Up!</li>
<li>Upload</li>
</ul>
<ul class="nav pull-right">
<li>
<div class="center-it">
<form class="form-search" action="/search" method="GET" style="margin:0; margin-top:15px;">
<input type="text" name="search_tag" placeholder="search..." class="input-medium search-query pull-right">
</form>
</div>
</li>
</ul>
</div>
</div>
</div>
</div>
In the official demo site it pushes down all the other elements which I would be happy with or if I can simply make it so that it is in front of the other elements.

Answer 1

The static position of your fixed navbar is causing this, the following css will override that and fix your problem (confirmed in chrome)
.navbar-fixed-top, .navbar-fixed-bottom {
position: relative !important;
}
