Hi.
I have this code that I want to use for a menue bar:

Code:
<div id='cssmenu'>
<ul>
   <li class='active'><a href='index.html'><span>Home</span></a></li>
   <li class='has-sub'><a href='#'><span>Products</span></a>
      <ul>
         <li class='has-sub'><a href='#'><span>Product 1</span></a>
            <ul>
               <li><a href='#'><span>Sub Item</span></a></li>
               <li class='last'><a href='#'><span>Sub Item</span></a></li>
            </ul>
         </li>
         <li class='has-sub'><a href='#'><span>Product 2</span></a>
            <ul>
               <li><a href='#'><span>Sub Item</span></a></li>
               <li class='last'><a href='#'><span>Sub Item</span></a></li>
            </ul>
         </li>
      </ul>
   </li>
   <li><a href='#'><span>About</span></a></li>
   <li class='last'><a href='#'><span>Contact</span></a></li>
</ul>
</div>
And CSS is:

Code:

The thing is that i already have a "div.categories.content" in my basic html (I cant acces the module since its a webshop i bought)
i wonder how I use this in this code to automaticly get the currect categories and subcategories into this menue?

What would you have done?

You can have a look at: ww w . amb e rbi rd . se (remove spaces obviously)

Thanks!
