In my shop there are products (chairs) with different sizes. so far so good. what I want is that when i select a size, for example XL that automatically the amount of pillows and their coloe can be filled by the customer.
For example: I select XL chair, with the XL chair there are 4 pillows so the customer has to be buy 4 pillows and they have to specify their color.
you cant buy 2 pillows with an XL chair.
If you buy a medium chair than you have to buy 2 pilows.
