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

[J. Bobby Lopez]

I also see that when I dump %cgivars after submitting a form with
multiple values selected in a 'select' element, that the values become
concatenated.

E.g (FormFu yml):

    - type: Select
      name: EmailDL
      label: 'Subscribed Lists:'
      options:
        - [ 'male', 'Male' ]
        - [ 'female', 'Female' ]


And resulting params (%cgivars):
   {
          ...,
          'EmailDL' => 'malefemale',
          ...,
   }


So I'm not sure how FormFu would deal with multi-valued selects in general?
