Thanks, that helps. Only this solution is limited to one field type this way. I would base/extend my ‘super-button-field’ on let’s say: the acf_field_page_link. If I want to also story more data (style, target, button text). I would hook into the update_value and render_field to extract the required data. And modify the html for the select and inputfields.
Not quite what I was hoping for 🙂 no offense. But already helps a lot.
Thanks.
