Advanced Custom Fields: ACF Country

This plugin adds a 'Country' field type to the Advanced Custom Fields plugin, letting you display a select dropdown of all countries in any language. It is designed for developers building multilingual sites or applications that need to collect or display country information.

• Localized country names: Country names automatically display in the current WordPress site language, using the CLDR data set for accurate translations.
• Flexible selection options: Supports single or multiple country selection, with the ability to allow or disallow null values and set a default country code.
• Enhanced UI with Select2: The field can use the Select2 library for a stylized, searchable dropdown interface, which can be enabled or disabled as needed.
• Customizable country list: Use the acf/country/countries filter to add or remove specific countries from the dropdown, giving you full control over the available options.
• Multiple return formats: Choose between returning just the country code or a full array with label and value, matching ACF's standard select field behavior.

Installation is straightforward via ZIP file or Composer. The field requires ACF 5.7+ and PHP 5.4+. It is maintained as an open-source project on GitHub, with support for contributions and sponsorships.
