Thank you for your response!Yes I have already enabled the quick add button. Because the product has 2 variants the "choose option" button shows like you have mentioned. I actually wanted more of the details to show in this quick add pop-up box, but ...

I am currently using the Sense theme and would like to add the option of choosing my variants in the quick add pop up itself, and not need to see the full details in order to pick the variant. I don't know how to add this option.
