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

[Michael Snoyman]

Hi Michael,

There's nothing jQuery or Javascript specific about a multi-select
field: it's just a normal select field with a "multiple" attribute. I
would recommend taking the selectField code from yesod-form and
modifying it to be multi-select. I'll likely do this myself
eventually, but it could be a good learning experience in Yesod (and a
great introduction to contributing to the framework if you're so
inclined).
