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

[J. Bobby Lopez]

I went ahead and ripped out $query->Vars() wherever possible on your
suggestion.  I have a fair handle now on populating the multi-select
fields, using $form->get_field() to focus specifically on a single
field.

I'm using the following to populate the multi-select, which _is_ working:

    $field->options($array_ref);

Though, I still haven't been able to highlight individual options as selected:

    $field->default($array_ref); # not working, but should be
    $form->default_values({ EmailDL => [ 'myvalue1', 'myvalue2'] }); #
not working, but should be

I am however, able to set 'selected' on the overall <select> tag, which is odd:

    $field->options($array_ref)->{attributes}->{selected} = 'selected';

..which generates this in HTML source:
<select name="EmailDL" id="EmailDL" multiple="multiple" selected="selected">

Although not what exactly what I want, it's helped my sanity somewhat  :)

looked at 'select_multi_value.t' and 'select_multi_default_values.t'
to make sure the syntax was right, but still no joy with setting
'selected' on individual options.

Likely I'm just doing something incorrectly, but no idea what.
Doesn't seem like it should be too complicated :\

Thanks again,
-Bobby
