Catalog menu

There is a site www.profotoplenie.ru
In the catalog there are levels and many sublevels. Now in the main menu only the main levels are displayed.
How to make so that by pressing level, subtotals opened?
For example:
????????? ?????????
- ????????? Kermi
- ????????? Korado
- ????????? Purmo

Can be eat any special module for these purposes?

Hi,
a long time ago.. if the Problem still exists: Normaly you need the Modul Catalog-Navigation (only works for Select and Taxonomie). There you can configure your Navigation like the normal Module from Contao.. like Startlevel 0 Stoplevel 0 and you get every Level.
