2A bone representing a country selection input field in a web application or form.

4The SelectCountryBone is designed to provide a user-friendly way to select a country from a predefined list of

5countries. It inherits from the BaseBone class and extends it to support country-specific functionalities,

6such as displaying country names and handling country codes (e.g., ISO 3166-1 alpha-2 or alpha-3).
