3 levels sub-forums issue

[gonabs]

Greetings to all Vbulletin.org community.

Hope some vb expert will help me :P

I'm using Cyb - Sub-Forum Manager (https://vborg.vbsupport.ru/showthread.php?t=201294) and I would like to know how to display sub-forums list in forumdisplay like in the forum index. Our forum have 3 levels:

Forum
-subforum
--subforum

We would like to display the --subforum listing when someone enter in -subforum Forumdisplay.

Thanks in advance!
