Hi thanks for your reply, this is no good for me as I do not want all the categories across the top just some of them, also i want other drop down links to be in there like a help one with a drop down to other pages in my shop.

Like i said i know how to create a drop down i just need to know what code do i need to add to the drop down to display the subcategories.

for example if i add this to the drop down menu

Code:
<div id="dropmenu1" class="dropmenudiv">
<?php for ($i=0, $n=sizeof($links_list); $i<$n; $i++) { ?>
  <li><?php echo $links_list[$i];?></li>
<?php } ?>
</div>
it displays all the main categories, but what code is needed to display subcategories for that category.
