I have Search API with Facets API set up. For my checkbox selections, how can I prevent the facets from hiding when they aren't available? I want all of the facets to be listed, even if not available.
I can't seem to find an easy way to do this.
EDIT: I may have incorrectly used the term "facets" here. I mean to say filter options. So, if blue, red, and green are options, but the only available results are blue, I still want red and green to display as check boxes.
