I'm using Drupal Commerce 8.x-2.x on Drupal 9.5.x. I need to restrict a particular product attribute to certain regions (regions selected via an attribute). My thinking is that the region is selected via an attribute; I can't see another way to do it for my means.
In my use case, regions are not location based geographical regions; they are locally defined regions, so I can't see a way other than attributes to define this.
So, for example, in attribute Region | Region A, only attributes Product Type | Types A and C are available, but in attribute Region | Region B, attributes Product Type | Types B and C are available.
How do I make the availability of attributes conditional upon other attributes?
Core components > Conditions is a start, but only works for payment gateways and promotions.
