I’d like to know if in the Extended version it’s possible to create a field that searches a term in an external database and displays a few suggestions while the post author is typing it. Sorta like the search box for categories does while you’re writing a new post, but in my case the search should be done on an external source. Then the post author would choose one option from the list returned by that search and the field would point to an external page.
I need this because the data in this field will come from a big database that isn’t connected to WordPress and it’s unfeasible to create new categories for each page it points to, as the database is constantly updated.
+1 I have the same question.
I need a field that query an external API with after the user has enter a minimal search (3 letters for example), send the query each time the search change and return a list of options that the user can select : key as object_id and name as label.
