>
> When using the Select component, you must explicitly add a blank value to the
> list of possible values if the selection is optional. It would be nice if
> there was greater control over this.
> 1) If the property is optional (as per validation via the validate parameter)
> then a blank value should appear.
> 2) When a blank value is added, there needs to be control over the label for
> the blank value.
> 3) It would be nice if it were possible to override the validator to "force"
> the Select to include a blank value even if required.
> I think it is reasonable for the blank option to appear first, before an
> option groups or individual options.
> This would be very useful for search forms, or forms where it is desired that
> the user be forced to make a selection.
