I think the "EPrints" way to do this is to build an InputForm ↵
component
plugin. If you take a look at
Plugin::InputForm::Component::Field::Subbject (phew) you can see how a
"widget" was built to enable searching of subjects (stuff to do with
_internal_ actions).

I've also done input widgets before that combine an InputForm component
with some AJAX (so you don't need to mess around with _internal_ action
passing).

All the best,
Tim.
