Advanced custom fields PRO: Create 3 cascading drop downs, using data from DB

Hi, I need three cascading/hierarchical drop down menus, populated by fetching data from database, set up in Advanced Custom Fields (ACF). [login to view URL] Will be used with Easy Digital Downloads plugin "Front End Submissions" (EDD FES), which allows users to create posts. ALL CUSTOM CODE IN SEPARATE PLUGIN In the database the data is currently like this, with example: School | School short name | Faculty | Course code | Course name | Mass inst of tech | MIT | Maths | MAT101 | Maths for beginners| In the finished drop downs, the user should be able to select school in the first drop down, then have faculties at that school be visible in the next drop down, and lastly the courses at that faculty should be visible in the last drop down. If you actually read this, start your bid with "Hola". Bids not containing this word will not be considered. In the drop down some of the current database values should be merged. Example: SCHOOL DROPDOWN MIT - Mass Inst of tech FACULTY DROPDOWN Maths COURSE DROPDOWN MAT101 - Maths for beginners I have spoken to the developer of ACF, and he says this is possible. See attached screen shots. I have also attached my current custom cascading drop downs, that work like I want, but hinder development since the code is in other plugins. All custom code in separate plugin. Please ask if you have any question.
