hey, nice tool, good coding!!!

i'm using version 4.0.11.

i've done many mods and hacks with this great shopsystem. But one problem i couldn't solve.

On the right side there is a navigation panel with the following structure:

MAINPAGE:
MAINCATEGORIES
-entry1
-entry2
-entry3
-entryn


Detailpage of one MAINCATEGORY:
MAINCATEGORIES
-entry1
-entry2
-entry3
-entryn

SUBCATEGORIES to the selected maincat
-sub_entry_child1_1
-sub_entry_child1_2
-sub_entry_child1_3
-sub_entry_child1_n

Never the less there are only maincategories with one "child".

If i've choosen one sub_entry, the following box shuld be shown
SUBCATEGORIES
-sub_entry_child1_1
-sub_entry_child1_2
-sub_entry_child1_3
-sub_entry_child1_n

That means if i've selected a product or one sub_category a box with all subcategories should be shown.


How can i realize this ????
i've there's somebody with icq, my uin is 123126029, please help me!!!
