Drop down dynamic menu

Question

Hi all. Please could you help with why this isn't working? I'm trying to create a navigation bar that links to my database, specifically I want to show all guitar bodies (drawn from mysql) on a drop down menu when the user hovers over Guitars on the top menu. I've downloaded something called Chrome CSS Drop Down Menu from http://www.empoweradvertising.com/36/dynamic-css-mysql-website-menus.html to do this. It's correctly showing the horizontal main menu items via the first part of the code below, but when I hover over 'Guitars' nothing happens. Am I missing something from the second part of the code? And is this a good way to do a dynamic nav bar or is there something else you'd recommend? Many thanks.
<div class="chromestyle" id="chromemenu">
<ul>
<?php do { ?>
<li><a href="<?php echo $row_rs_menuitems['link']; ?>"><?php echo $row_rs_menuitems['menuitem']; ?></a></li>
<?php } while ($row_rs_menuitems = mysql_fetch_assoc($rs_menuitems)); ?>
</ul>
</div>
<!--1st drop down menu -->                                                  
<div id="dropmenu1" class="dropmenudiv">
<?php do { ?>
<a href="<?php echo $row_rs_bodies['link']; ?>"><?php echo $row_rs_bodies['name']; ?></a>
<?php } while ($row_rs_bodies = mysql_fetch_assoc($rs_bodies)); ?>
</div>

This is a very helpful execellent sample code.
However, If I'm using Model-View-Control approach, then what's the way of applying these codes
to each indivisual file? Say, I have 20 files and only 4 of the 20 need to be treated as they like
to have drop down menu in particular column(s)??? How could the custom tag be applied as the
controller tells the view to present these special treat? or it is not possible (I have to treat each
file, filtered by controller -- one by one as it encounters the special need)?
