I think I improved two things in the version of lines 20-26 below:
1. I gave the div an id rather than a name
2. I gave the div a style of "display:none" so that it's hidden at
every startup of the view

<%# = image_tag "DownArrow.jpg" options =
{ onclick=page["vendor_droplist"].show } %>
<br>
<div id="vendor_droplist", style="display:none">
<%= select_tag "test",
options_for_select(@current_vendors.collect { |v|
v.nickname }),
{:multiple => true} %>
</div>
