I have 1 product display connected to 3 product variations, each with its own color. Automatically Commerce adds ajax and other fancy features to my node/xxx page so I can switch between the different colors and the image, price etc. will change.

But my problem is that one attribute is always selected by default. I want the user to -have- to select an attribute when he tries to add his product to the cart or else he'll get a warning that no attributes are selected.

I want this feature because I want to display a default "collection" image showing all 3 colors together before the user has made a selection and when he selects a color it switches to the image for that color. I have one image field for my collection image on my product display type and the variations have their own image field for the image displaying the selected color.

I was going to code all this myself, but seeing as Commerce ships with most of the functionality I was wondering how easy it would be to modify the existing functionality to work like I want.

Thanks in advance.

Sincerely,
Øyvind Strømsvik
