I needed an ACF filtering plugin due to the design of my company’s website. This plugin is working perfectly except for one thing. Not allowing support for ACF Field Groups set to display on Post-Taxonomies. I have several product categories, each contain their own unique set of ACF fields to display on the front-end. Now, I have to go to my ACF fields groups and set them to display on Post-Type Product. This means every product has every category’s ACF fields in the back-end. Not a huge problem…but it would be nice to be able to keep my ACF Field Groups set to Post Taxonomies so that I can keep the back end clean for each product. What is interesting is that if I set the ACF fields group to Post-Type Product, the widget for ACF filtering shows the ACF selectable field in the widget area, but then I turn the ACF field group back to Post Taxonomy…the widget continues to work on the front end, but the back end, the select box is empty on the widget. Appears to have the functionality, just needs some tweaking?
