I have the following fiddle: <http://jsfiddle.net/g4zLzyqf/>

Partial HTML:

```
<div id="navMenuHolder" class="navMenuHolder">
    <nav id="navMenu" class="navMenu">
        <ul>
            <li class="active">
                <a href="index.php">Home</a>
            </li>
        </ul>
    </nav>
</div>

```

As you can see submenu under `Directory` has extra space underneath.

Please help me so that the submenu is dynamic and only expands based on the amount of item in the submenu.
