I want to add the attributes in the category listing. When a user click on a category, it displays a list of all products in this category with a link to ?Add to Cart?, I want to add above this the product attributes to allow user to select the option he wants and add it directly to the cart without taking him to an additional page to select options.

I would like to display outfits. An outfit consists of different cloth in different sizes. A bundle e.g. may have a t-shirt (which has different configurable sizes like S, M, L,?) and a pair of jeans.
