I've these custom posts
- Music Festivals (the event, globally)
- Editions (each year the festival is held, child of "Music Festivals")
- Stages (each stage that exists on each year, child of "Editions")
The I have:
- Shows (each perfomance on each "stage" of each "edition" of "each music festival")
I need to be able to chose, on each "show", the "music festival" and then the "editions" dropdown menu would filter itself to only show editions from this music festival and then the "stages" dropdown menu would filter itself to only show stages from this edition.
Is this even possible? How can I achieve this?
