Limit selection of countries in Contry Picker widget

Is there a way to limit choice of countries from country picker widget to certain list (say European countries)?

I would like to apologize for any inconvenience, however, I'm afraid there is no option for the Country Picker widget to only show specific countries.

You can use the basic drop-down field and list all the specific countries you would like to include in your drop-down.

Or, you still want to include the flag images of each country, I suggest you use the ddSlick Dropdown widget instead.
