Tree or DHTML menu

Hi to all, I’m a new user of this forum.

I have implemented the DMRY Ağaç Navigasyon Menüsü 1.0 (http://www.dmry.net/dmry-agac-navigasyon-menusu-10?cl_lang=dil-en)
in this site (you can see on the right column, it’s the one with the icon):
http://www.ambientemola.it/html/

It works fine, but the problem is: it doesn’t link and display the pages, only display and link the child with respect of the page.
So for example I put this code
<?php DMRYTreeMenu(‘child_of=4&sort_column=menu_order&sort_order=asc&title_li=’); ?>
but the page with id=4 is not displayed and linked, only the subcategories.
How I can obtain this? Or there is some other menu that do this?
Thank you.
