[html-formfu] Populating $form_input with 'select' element options?

[J. Bobby Lopez]

Hello Carl,

Thank-you for responding.

How would this work with multi-valued selects?  Can default_values()
still be used to show which items are selected by default, or would
default_values have to be avoided altogether for multi-value selects?
