Thank you for contacting us. There is no direct option to set the default country. However you can use our hook system. For example:
$command[‘on’] = array(‘select-1551968842703’);
In the above code, replace 13452 with your Form’s ID. “select-1551968842703” is the field name for country dropdown. You will have t replace with your field’s name. You can get your country field’s name by locating it in the preview mode (right click on the field and click on ‘inspect element’ option).
add the above code within your theme’s functions.php. If you can share the URL of your Form, we can provide you exact code.
