In my website I will be selling perfumes from a lot of brands.... so in order to make it easy to the consumer, I would like to add a drop down table to my zen cart but I am not sure how to do it or of it is possible at all.

I am thinking three options:
#1 have as top categories: women & men
then when the clicking on one of them, it will direct them to the page that has a Drop down table by brands.

#2 have two sideboxes: women & men and in each of the appearing a dropdown table (as the demo MUSIC GENRES)

#3 have as top categories: women & men
then add to each of them a subcategory BRANDS and in there list all the brands linkable to take the consumer to the page that lists all the perfumes of the selected brand.

PLEASE advise which option is feasible in zen-cart and what steps to follow in order to do it.

Thank you!
