That file contains all the country name. You can keep the one you want and delete other countries. Currently, we do not have an action or filter to override this setting externally. So you have to edit the source directly.
I have country The Netherlands, and want to add states to it for picking this in dropdown menu when creating an new contact. I can pick country the netherlands, but i cannot pick states.
I added a php file with the states in it, but that does not do the job.
@leo,
You can easily add the necessary states according to your needs.
Here is the file location: “wp-content\plugins\erp\i18n\states”
See the BD.php and you will get the idea on how to add the states.
