Hmm, this would be a nice feature to have, because I can see it being slightly confusing for customers who see the options button.
Perhaps a work around would be replacing the Options button with a new button image that says 'Details'.
Also, I have another question in regards to product variants -
Is it possible to create a drop down menu that forces the customer to choose one of the options when purchasing? So far I've only accomplished creating two seperate drop down menus, with 1 item in each - but I would like a single drop down, including both items.
I'm not entirely satisfied with the radio buttons, check boxes & drop downs. I have found that with multiple variants, the customer is able to check each of the radio buttons, and each button remains checked while the others are also checked - without any way of un-checking the buttons. The only way to fix this is to refresh the page. This would be confusing to the customer, thinking they are now purchasing both options, and could lead to frustration.
