Forum Navigation collapsable

[stonner]

Hi,

I made a new module in vbadvanced for the forum navigation: www.schuelercommunity.com/forum.php

Now, I'd like to make main forums such as "Lehrerzimmer" and "Lounge" collapsable. They should be collapsed by default.

I'm using a template module with the following template-content:

<tr class="alt2">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=6">&raquo; <b>Lehrerzimmer</b></td>
</a></tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=60">Fragen zu SC</a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=10">News</td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=40">Lob, Kritik & Vorschl?ge</a></td>
</tr>

<tr class="alt2">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=7">&raquo; <b>Lounge</b></a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=20">Schule allgemein</a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=11">Plauderecke</a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=27">Stell dich vor</a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=29">Game Lounge</a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=12">Marktplatz</a></td>
</tr>
<tr class="alt1">
<td class="smallfont"><a href="http://www.schuelercommunity.com/forum/forumdisplay.php?f=52">Arbeitswelt</a></td>
</tr>

I appreciate any help!
thank you
