I'm not 100% sure if I get what you want. But if I do. Try to edit the
forumhome_forumbit_level1_nopost template to this.
Code:
<if condition="$childforumbits">
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">
$childforumbits
</tbody>
</if>
Then creat a new forum and click no on "act as forum" and let all your forums have that forum as parent. That would give you a list with all your forums without the "head" part.
