Developers can customise the behaviour of the plugin through filter hooks. There are some useful filter hooks supported by this plugin, and by Gravity Forms itself.

- string $country_code
- return string
Developers can add their own country and state/province definitions, overriding those provided in the plugin. See the folder includes/countries/ for examples.

Developers can add or remove countries that should be supported for Smart States dropdowns.
