Excellent

Excellent and useful plugin, unfortunately list countries are not accurately by alphabetical order.
Thanks to the community, add this to you function.php and it will work like a charm.

function wpcf7_listo_ordered( $data) {
sort($data);
return $data;
}
add_filter( ‘wpcf7_form_tag_data_option’, ‘wpcf7_listo_ordered’, 11, 1 );
