Exactly what I’m looking for but for a soccer team 😉 . I’m investigating on this and check some solutions.
It is not possible on php side because there is no hook when you add/remove an item in one field.
Seems to be possible using JS API… but I need to pass items list (available in PHP)
What I’ll try :
managing add/remove hook using JS API
launch an ajax request that manage the selected list (as global) and add/remove items depending on the selection.
I need to filter the available items through javascript by reading through ajax the PHP list …
Should do the trick but it seems hi level dev…
