Need dropdown filter w/ the choices pulled from CMS


Currently looking to build drop down filters. First tried using a form block and form elements following the lead of F’insweet but the problem is that the filter elements need to also appear on each card. I say “card” because the site filters a collection list with all info coming from the CMS.

Now, I tried to use drop downs but they are just link blocks and do not have the ability to filter my list. Need a dropdown filter with the choices pulled from the CMS. Solution?
