Hi @Epik
Thanks for the feedback. Yes some sort of ‘clone’ or ‘ditto’ field would be awesome, and I hope to add one in soom.
For the time being, I would create a select field in each field group called ‘counties’, but I would not add in any choices.
Use a filter to hook into the field and populate the select field choices dynamically. This means all your country fields will load the choices from some PHP. And you can then store all your country data in PHP, or even a json file.
