I too have resulted to WP GridBuilder for filtering of ACF Fields – however I cannot for the life of me get the ACF filter facet to work. The GridBuilder docs are of no help and I’ve watched several “training” videos that seem to have the same issue as I have, i.e. the filter never displays on the frontend.
I have Custom Content Filter enabled.
Is there some sort of function I need to add to my functions.php to get the wpgb-content to display?
Hope you can help…
