Woocommerce Addon – conditional display options

I am working with an overseas developer and am in need of some direction. I would like to set up 1 conditional display option in the attributes for the products.

I would like to give my customers the ability to select a color of, say, a hat. Once the color is selected it will then display only the styles of hats that are available in that color by displaying a thumbnail of the various hats. I have looked up and seen that gravity forms can give you the options but it only uses text and drop-downs, nothing graphical for my customers to view.

Does anyone have any direction for an add on that I can research?
