I currently have a custom taxonomy select field called "Location" and another custom taxonomy called "Company". What I would want to do is to hide/show the Company check-boxes based on the chosen Location in the select box. This is for the back-end.
The Person custom post type is associated with a Company and each Company is associated with a Location taxonomy. Advanced Custom Fields conditional logic does not extend to taxonomy fields and if anybody knows a way to go around this limitation that would be super awesome.
I am looking for taxonomy-related conditional logic as well and I found a post on the ACF support forums (http://support.advancedcustomfields.com/forums/topic/conditional-logic-using-taxonomy-field/) that shows many other people looking for this as well. However, there was no solution or answer in this post (most recent post asking for help being 6/7/16). Perhaps it will be solved in the future given the many requests, but no answers there at present.
Seems that the best option for now is to use jQuery on the backend.
