[Haskell-beginners] Options for creating a multiple select form via Yesod

[Michael Litchard]

Hey! I just added multiSelectField to the Forms library. I'm only
getting the first value selected, but I think that's because of how
I'm using multiSelecrField. I'm going to try to change the client code
to fix this. I'll let you know how it goes. when I get a
maybeMultiSelectField added I'll show you what I have. What would be
the best way to submit this?
