Sorry, I think my question was confusing. What I want to do is
allow the user to either select a user from a drop down list

manually type in a name themselves.
In the same field that would require a hack of the first water.
Way above my pay grade. For me, anything which equates an existing
user object with a string typed in is likely to end in misery.
Otherwise a separate CharField for the typed in name and null=True
and blank=True in the ForeignKey ought to work.

Indeed, what you can also do - besides the nullable FK, is process
that in the Form where if the FK is null and the the charfield is not
None, then create a User (maybe non active) with that name and assign
it to the FK.
It will depend on the use-case requirements but I think that could get
slightly messy. You need to ensure you are not creating duplicate
people. For example you would likely need case-insensitive names.
Thanks for your reply

Yes. Make the ForeignKey in the model null=True and
blank=True so
it can
exist all alone. Then you can limit_choices_to whatever
whatever
suits
your requirements ...
