Remove class on click and add to another element
<p>I have a navigation menu and when 'contact is clicked' a div opens at the top of the DOM, I want to add an active state to contact using jQuery but for some reason cant get it working. </p>

<p>I'vbe made a fiddle to hopefully explain better...</p>
