It would be extremely useful if we could consume REST API data within the form element (server-side).
For example, I wanted to use a form element inside a query loop where I queried stores from another website and sent an email based on each store’s ACF email field.
I understand the technical limitations, but maybe you could implement a field where we can provide additional context — for instance, I could include my post_id (from the other site), and then use a backend filter that references this ID to define the email on the backend.
