How to fix my navbar - html

Question

I have looked at other questions, but I just can't seem to fix the dropdown menu in my navbar.
I'm trying to make a dropdown menu like the one that is here, it's in the top right corner.
This is my code:
<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<!-- You'll want to use a responsive image option so this logo looks good on devices - I recommend using something like retina.js (do a quick Google search for it and you'll find it) -->
<a class="navbar-brand" href="#">Loveland Tigers</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse navbar-ex1-collapse">
<ul class="nav navbar-nav navbar-right">
<li>About</li>
<li class="dropdown">
Teams<b class="caret"></b>
<ul class="dropdown-menu">
<li>Freshman</li>
<li>Junior Varsity</li>
<li>Varsity</li>
</ul>
</li>
<li>Contact</li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container -->
</nav>
The dropdown menu does not show up when I click on the little arrow.

Answer 1

Remove those unneccessary classes from navbar-collapse div:
<div class="navbar-collapse">
<ul class="nav navbar-nav navbar-right">
<li>About</li>
<li class="dropdown"> Teams<b class="caret"></b>
<ul class="dropdown-menu">
<li>Freshman</li>
<li>Junior Varsity</li>
<li>Varsity</li>
</ul>
</li>
<li>Contact</li>
</ul>
</div>
<!-- /.navbar-collapse -->
