Is it possible to prevent the customer from designing one view if they have selected another view?
For example, I have a t-shirt with a front and back print area. If the customer chooses to have the front side printed, the back side is disabled, but if they choose the back side print area, then the front side is disabled. This would allow me to have multiple print areas but the customer can only chose one print area.
There is currently no way of doing this. You would have to create two different products with different customizability.
This would patch up the problem that we can't add to the cost for printing on the front AND back of a t-shirt. At least it would get limited.
