Yes, you can categorize your products easily.
Santu supports a very powerful category function, which allows you to add custom categories to all your products.
You can also create multiple levels of categories, such as Shoes / Men and also list products in one or multiple categories.
If you add brands to your products, a brand category will automatically be created, and specials will automatically be listed in the specials category.
You can set up categories in My Store - http://app.santu.com/buynow/category or you can add them while you generate the products, using the Category tab.
