X-Cart forums - Menus menus and more menus

I am trying to get menus the way I want them and am going around in circles. What I would really like in the absence of flyout menus (have gone down the fancy cats and dhtml path and come back again) is to have a menu that is automatically generated and that includes all of my categories (or rather subcategories) with a number of above say 500 or all of my subcats that fall underneath another subcategory so an automatically generated www.naturalvetcompany.com menu on left hand side - does anyone know how to do this?

and /or if I had cats:
for dogs
>conditions
>arthritis
for cats
>conditions
>arthritis

I would also like a menu that changes dependant on where I am so:
on www.naturalvetcompany.com
if I click "for dogs" i get conditions down the side and the results are only those in the arthritis section for dogs. Is that too hard I wonder. Also if I then generated the html pages would it all go pear shaped. If I havent selected anything from the menu then it contains all of the products for arthritis for cats and dogs

thanks again all
