[trafix]

I am trying to add collapsable genres to my vb jukebox i have used the code belos to form the genre sections, and the sections do open and close when clicking the image ..... however any that i have closed once i refresh display as open again ....... what do i need to do to fix this so colsed genres stay closed on refresh?

Tnx in advance

 <tbody>
 <tr>
  <td class="tcat" colspan="5">
   <a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$jbgenre')"><img id="collapseimg_forumbit_$jbgenre" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_jbgenre}.gif" alt="" border="0" /></a>
   $genrename[genre]</div>
  </td>
 </tr>
</tbody>
<tbody id="collapseobj_forumbit_$jbgenre" style="{$collapseobj_jbgenre}">
