ok – thank you for your feedback.
I don’t know how to write javascript etc, but I will give it a go.
Is there any way you can help with the writing of the script?

long story short:
If you buy half or a whole lamb, there are different sections to the animal (Leg, Loin, Shank, Shoulder etc) and there are multiple cuts that you can select from each section of the animal. Leg = 3 options, Loin = 5 options etc. And the customer is only able to select one cut, because when an animal is slaughtered, the customer has access to one cut from each side.

Does that give context?
