Hello!
Short history of issue:
Created custom fields with Crocoblocks (Meta box), but it`s checkbox is not compatible with ACF and can not get custom fields in WCFM products.
If custom fields done with ACF then in return I can not get to work SmartFilter by Crocoblocks.
Solution was to use Crocoblock and WCFM product custom fields, code in functions.php. Resulting checkbox to appear in WCFM product and works with SmartFilter.
As issue went further in Elementor template we could get checkbox Label, instead it showed Name (data base entry).
Issue:
Now to show checkbox values Shortcode was created, but the issue is that Ajax Search Pro does not show results anymore. Looks like search reads values but does not display them. Product with selected value appear in search.
Thanks in advance, looking forward hearing from you.
