create name/value pairs?

[scottnath]

I want to be able to create custom fields, but have them be defined by
flutter. For instance:

I am creating a database of plays I was in and part of that will
include cast and crew lists. Now, inside the write panel for entering
a play I have added a group called 'cast'. Inside this group, how
could I have pairs? Rather than a setup like:

Group: Cast
Field inside group: Cast Member (John Doe)
Field inside group: Character (Hamlet)

What I need is this:

Group: Cast
John Doe (name) Hamlet (value)
Jane Doe (name) Ophelia (value)

Is there a way to do this?

If not with flutter, does someone know of another plugin that can do
this?
