title: Dojo get next sibling based on current event target
body: <p>I have this dropdown <a href="http://jsfiddle.net/zV78L/77/" rel="nofollow">menu</a>, and all i want to do is upon firing the onmouseenter event, to change the border-left of the targets next sibling to white. So far i can address the currentTarget's border-left with ease, but i cant find a way to do the same for the next sibling. Any ideas ?</p>
