This feature should have the Brand/ Manufacturer type. For other types variants will not be displayed
They are. I have two features in Brand/Manufacturer type - one Brands and another Publishers. One of them is registered as Filter and has filter_id, the other is not promoted as filter. So the question is how to show all Brands that have only feature_id and no filter_id
It's more resourcefulness than solution: Ð“Ð¾Ð»ÑŒ Ð½Ð° Ð²Ñ‹Ð´ÑƒÐ¼ÐºÐ¸ Ñ…Ð¸Ñ‚Ñ€Ð° :-)
The main issue with the Authors was that there can be many of them for one product, and they should be entered one by one, using the only possible Multiple option in the Type selection. Brands however accept only one value. So, I introduced a second Multiple feature and called it Co-Authors, moved there all co-authors and transformed the Authors type into Brand type.
