I recently saw this functionality was added to Webflow's native filtering system, but I can't remember if FS's CMS filter uses Webflow native filtering at all...
Evandah S. is it a data issue? I opened up 4 or 5 news articles within the news collection and only saw the each article was only tagged with a single category. All of the related fields at the bottom were empty.
yeah its definitely a data issue, or at least I'm not really seeing how you are creating the relationships from news article to type, main category, and sitewide tags.
