How to use CS FORMS to filter a ACF CPT / ACF Taxonomies on an Archive Layout

Thanks for CS forms ! but have tried and cant work out how to use it for ACF CPT / Taxonomy filtering (using an Archive Layout not a Page/Looper), and there is no documentation or videos I can find to help.

eg. https://theme.co/docs/cornerstone-forms-overview … has no details regarding ACF CPT and Custom Taxonomies filtering.

Uploaded the “Filtered Archive” template as a starting point.
Could not get that to work with even POST / Post Category connected to my ACF CPT?

Any chance you could please log in and let me know where I am going wrong?

  1. Updated PRO Theme Updated, Activated CS FORMS. PHP v8.3
  2. Uploaded the Filtered Archive Template (I know its for Posts but thought a good start?)
  3. Created a new Archive layout for Filtered archive from the new template
  4. in the archive layout,
    Form element, Ajax On, Change Selector = #posts (matches column that contains the looper consumer)
    Changed the Archive Settings to Post type = my ACF Custom post type (ewc-project)

ACF Post type ewc-project: Taxonomy project-sector is linked to the Post type, and Adv sett: URL --> Archive ON
ACF taxonomy field key = project-sector (In the field group it Saves Terms, Returns Term ID (but tried objct ID as well), is a Radio Button)

Form Checkbox List setup (to select one or more project-sector):

  • Option Looper provider : All Terms, included my Taxonomy = project-sector… values all come through on the screen ok.
  • Validations: did try array and delimiter.

How do I get the filtering to actually to work / do anything?

Is the issue with the options setup (in the General: Name / value… to link ACF CPT to the background GET query)??

On the front end… the checkboxes do nothing.

How do I connect CS Forms for Archive Layout filtering with a ACF Custom post Type / ACF taxonomies?
Thanks in advance.
