Its possible. This is what I use on my forumhome template to get the desired effect you are seeking:
HTML Code:
<!-- Start Empty Shell -->
<table width="100%" cellpadding="0" cellspacing="0" border="0" class="tborder">
<tbody>
<tr>
<td class="thead"><a style="float:$stylevar[right]; text-decoration:none" href="#top" onclick="return toggle_collapse('forumhome_empty')"><img id="collapseimg_forumhome_empty" src="$stylevar[imgdir_button]/collapse_thead$vbcollapse[collapseimg_forumhome_empty].gif" border="0" alt="" /></a>Your Title</td>
</tr>
</tbody>
<tbody id="collapseobj_forumhome_empty" style="$vbcollapse[collapseobj_forumhome_empty]">
<tr>
<td class="alt2" nowrap>Your Content</td></tr>
</tbody>
</table>
<!-- End Empty Shell -->
