Hi Nicolas,
2. Hmmm, not obvious!
You say "when you unpublish a variant, the choice is removed from the caracteristic dropdown" -- I only get an Out of stock message
But you also say "you still have all the possible values in the characteristics dropdown..." -- Yes, that is what I get... And that is what is confusing me (and probably Max) -- You STILL can select S & Yellow.
I (we) were expecting that if you select S in your example above, then Yellow should not appear in the "colour" dropdown!
I did some tests on the demo site and unless I am really not on the same wavelength with you (and that IS probable!), all options remain selectable in the dropdown lists whether or not a variant with those caracteristics exists.
I wish you can prove me wrong !
So, at this stage, I see no alternative but to use the modified "Out of Stock" message to explain that a variant does not exist.
