Set modules to be expanded to collapsed dependant on some condition

[richy96]

Hi
hopefully the title explains this but anyway:

What I want to do is set things so that some of the modules that make up the vb pages are either expanded or collapsed dependant on some condition in the template

I am using code based on this generic stuff for expandable sections

<tbody>
	<tr>
		<td class="thead">
			<a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('give_a_table_id')"><img id="collapseimg_give_a_table_id" src="$stylevar[imgdir_button]/collapse_thead$vbcollapse[collapseimg_give_a_table_id].gif" alt="" border="0" /></a>
			any information this is the header
		</td>
	</tr>
</tbody>
<tbody id="collapseobj_give_a_table_id" style="$vbcollapse[collapseobj_give_a_table_id]">
	<tr>
		<td class="alt2">any information inside the module</td>
	</tr>
</tbody>

It works but I must admit I don't really understand what makes it expand and collapse (like the generated html source looks the same in my browser regardless)

Anyway what I want to do in my templates is something like

<if condition = something or other>
display module expanded when page is generated
<else>
display module collapsed when page is generated


Obviously the user can still collapse/expand manually using the little chevrons

How do I go about doing that?

cheers
