@rendermanGL,

I am wondering if you have a readily available solution or something in the making for functionality whereas GeoIP data is pulled before the form loads and then the matching country flag is fetched based on the IP address.

Alternatively and equally cool way to handle this would be based on user input - Country field should be on the form before the phone number and once a user selects the country the form would update the country code/flag in the phone field accordingly?

Thanks

How do I do this in the wordpress astra theme? thank you

I have the same issue i am using astra theme for some reason when i put the above code it works for the first time but when i reload again , the default country is gone again ,
