I was just wondering if a drop down menu could be implemented to increase the categories beyond a single industry type?
Some industry types have specific sub-categories.
A simple new field in the db could allow for additions to the categories admin section where a parent could be selected to add a new category too.
It can also be extended further to allow multiple sub-categories.
Then a simple flash, CSS, ajax or javascript drop down menu could be attached to the main menu to allow for much more menus and therefore categories.
