igi2011:
Just a quick update in case anyone else has the same problem... I've managed to get round this (up to a point) by using a blank sidebox in place of the category menu on the left.
As we already had one instance of blank sidebox, I changed all filenames and references within these files from "blank_sidebox" to "category_sidebox".
Yes... a good solution!
As you know, however... the list in the blank sidebox must be MANUALLY edited.
I was actually wondering if this couldn't be achieved by using two PRODUCT TYPES (Product General and Document General), where you create similar categories, then LINK all products to the relevant categories.
You could use the documents categories sidebox for the left, and hide the convetional sidebox, but continue to display categories on main page.
we did something SIMILAR HERE.
See the nav cat tabs menu (horizontal menu bar) and the cateogries menu are different... The menu bar uses product_general and the sidebox uses document_general
