Sadly i would like to ask you to refund my purchase.
I tested MetaBox and really liked it. But i tried migrating some acf frontend forms. I am missing many filters e.g. for ajax results that allow a truly dynamic frontend form. Also i cannot find any js api sadly. I really like the relationship and database stuff metabox has and hope the code api is improved and becomes as versatile as the one acf has.
@Arno you are right, but i was talking about code filters not visible ui filters 🙂 E.g. i want to create dropdowns with truly dynamic data that is catched each time a dropdown is opened. Thats possible if select fields support ajax and the ajax call has a filter.
