Different IDs For each Wordpress Submenu?

Question

Does anyone know of a way to add a unique ID to each submenu wordpress Generates? As of now, WP generates:

<ul class="sub-menu"></ul>

Ideally, I'd like it to generate

<ul class="sub-menu" id="radio"></ul>

So that I can assign a different style to each sub menu generated via css.

Any help is appreciated.

This may not be the best way, but it did the trick for me..

<script>
$(function(){
    var i =0;
 $('ul.sub-menu').addClass (function(idx) {

     return "item-" + idx;
 });
 });
 </script>

It appends the class item-0, item-1, etc to each sub-menu it finds.
