Tag PredefinedOptions is used to output all options, associated with a given field, e.g.
- country list
- state list
- possible link statuses (Active, Pending, Disabled)
It has several special parameters:
- "has_empty" - adds first empty option before other options
- "empty_value" - value of first empty option
Problem is that there is no way to specify that empty options's text. Now there is with this patch and new "empty_label" parameter.
