Country Dropdown Data Type

Used the uComponents country picker dataype long time ago.

In version 7 (7.1.8), how can I create a data type (dropdown list) property for backend user to select a Country?

I have cheched the projects page and they are all pre-v7.

If someone can chip in what is the ideal/quick way to add country dropdown to be used in document-type, would be highly appreciated.

cheers
