Manufacturers As SideBox - But Not as Form

http://twoturtlesart.com/zen-cart/

I want to "Manufacturers" as one of the side boxes. However when I set it to show in the right sidebox in the Admin console it shows up as a "form".

The other sideboxes are lists.

Here is the html generated, but for the life of me I can't find where to find and edit the form, form method, etc. html code:

<div id="manufacturers" class="rightBoxContainer" style="width: 150px;"> <h3 id="manufacturersHeading" class="rightBoxHeading"> </h3> <div id="manufacturersContent" class="sideBoxContent centeredContent"> <form method="get" action="http://twoturtlesart.com/zen-cart/index.php?main_page=index" name="manufacturers_form"> <input type="hidden" value="index" name="main_page"/> <select style="margin: auto; width: 90%;" size="3" onchange="this.form.submit();" name="manufacturers_id"> <option value="">- Reset -</option> <option selected="selected" value="16">Carol Ellison</option> <option value="10">Deb Test</option> <option value="18">Doug Napier</option> <option value="15">Heinz Brummel</option> <option value="11">Jay Pond</option> <option value="17">Mary Jo Mercy</option> <option value="14">Tom Herzog</option> <option value="12">Tom Thorson</option> </select> </form> </div>

Actually a dropdown rather than a form. If you search the Free Software Add Ons for 'manfacturer', there are a few mods, including one that replaces the dropdown with a list of manufacturers' icon images. You might be able to adapt that one.
