I don't know if this is already possible, but it would be nice if we could hide the add-to-cart button until at least one image element is added in the FPD.
For example, in my application I would like the customer to have to hit the "Customize" button and then add at least one graphical element (text or image) before the add-to-cart button appears. Once they add a graphical element, the price is no longer zero and so the add-to-cart button will then appear. This is because, I do not sell blank printing materials (with a zero cost).
Thats possible, there is an option in general settings "Customization Required".
I understand. However, if the customer adds like one image or text box, then deletes it, the price still stays the same. It does not go back to zero.
I cannot find that "customization required" in general settings
