You could modify the intermediate.php to use a spry accordion panel, place the catagory names in the according labels and the products in the child accordian panels. This is not something we can offer support for however.
To show the category name, use the following code:
<h1 class="larger">Product List <?php if(isset($_GET['CategoryID']) && $_GET['CategoryID'] != "") {?>for <?php echo($row_WADAProducts['CategoryName']); ?><?php } ?></h1>
