Collection A has a direct reference to collection B.
On the collection A page template I want to include an option to select one of the collection B items (don’t mind if it is via selector, radio box, …).

Link the Field label to the contact name. (get text from contacts and choose name)
Add an Html embed right below the radio button field (inside the dynamic item) and add the following code, replacing the NAME & EMAIL with dynamic fields:
