Category listing mod

[feenix]

Hi all, am having fun with my first experience using osc to build a shop front for a client who is selling kids clothes. Am hoping that someone here can offer some advice on modifying the category listing.

I'm trying to work out whether I can use a check box (or similar) to select gender (boy or girl), which would then only load the categories which contain that gender as an attribute. In other words, a customer selects "boy", which would then populate the category/product listing with only boys clothes (eg, there wouldn't be any dresses or skirts).

Is this possible or, if not, has anyone implemented something that can do something similar to this?

Appreciate the help
