[Solved] Type selectbox, optgroup possible?

Hello simplify,

AFAIK, not as a parameter in field configuration.
What is the amount and source of your data?

Some Ideas / Workarounds

• Select field has a parameter Color Separator. You might add the Region name instead of a color. In a custom form input template, you might parse and group the values based on the RegionName. Requires PHP/arrays knowledge)

• Select field could also be populated by a custom SQL.
  (you might store your Regions/Cities in extra DB table, or maybe utilize J! Cat/Art, or J! hierarchical Tags? Still needs work on a custom form input template, to create the necessary optgroup markup...)

• Have a look at commercial field Multi Level Select

• What about Category/Subcategory structure?
  You can disable submission for parent categories (Regions). On submission form and category selectbox they will show-up as visual separators!
