Item Groups invalid variants
I'm useing Item Groups. I set up 3 attributes with 2 options each. That
would create 6 variations, but 2 of those are invalid, so I deleted the
corresponding Items. This way the invalid combinations can still be selected,
but generate message in the online store “Temporarily unavailable” Is there a
way to pre-filter the attribute dropdowns based on what value is selected in
the previous one, so that the invalid combinations won’t even show?
