@PolarRacing A recently revived old thread here made me realize that when using the orderby_field query parameter, there seems to be an attribute that can be used called hide_empty=true that hides items that don’t have any value in the field that’s being used to filter them. You could try using that attribute but my assumption, given the fact that this doesn’t seem to be documented, is that this might have been a one-of feature added to the orderby_field parameter but might not have been extended to work with the other attributes. I’ll have to check in with the devs to see what the best approach here is here to create the maximum flexibility across the board. Just thought I’d chime in with that newfound information.
