I have a navbar with a dropdown menu. This dropdown menu has a few children, one of which is also a dropdown list (i.e. Brands). When I click this dropdown list and then close it up again with the toggle caret, the 1px border around my entire navbar-collapse div disappears. I can't see what causes that to happen.
I also get weird border changes when I click the Brands dropdown, toggle it closed, and then try clicking a regular link in the dropdown menu (i.e. About).
Here is what the code looks like:
<div id="navbar" class="navbar-collapse collapse"> <ul class="nav navbar-nav"> <li><a>About</a></li> <li class="dropdown"> <a class="dropdown-toggle" data-toggle="dropdown">Brands<span class="caret"></span></a> <ul class="dropdown-menu"> <li><a>Brand 1</a></li> ... 
<li><a>Brand 1</a></li>
