Hi, does anyone know how to block users from adding to categories until they reach the end of the category tree? For example, if a category is...

this/is/the/example/category/tree

they cannot add anything between 'this' and 'category', only into the last one, being 'category'?.

I know there is a mod "Add/Mod_only_in_special_cats" which is probably what I need, but could it be done simpler using a <%if category%><%endif> on the 'add link'?

Anyone got something like that working?

Cheers

Regan.
