1.5.6.4 full path url problem

Hi guys, after a lot of search i did not find a solution to my problem.
i have a structure like this:
category
-subcategory
--sub subcategory.

When i select either category and first level subcategory i have an url which is:
category&path=90 or category&path=90_88 which are good to me cause i can use parent id ( 90) to set different css.

when i go in the sub subcategory i miss the parent path and my url became:
category&path=88_92 (the 90 is missed)
so i cannot assign the correct css

is there a way to have an url like category&path=90_88_92 ?

for specs i use a free custom template which i hardly modified.

thanks

seems no way.. thanks to all who watched

OpenCart did it differently, the more confusing way.

You can still do what you want to do, just not how you want to do it.

Try this...

Set up your Categories
and SubCategories

Then for all other minor categories

Make Attribute Groups
and for even smaller categories...... Attributes

Will this work?

thnks i will try and let you know!!
