Tony asked 3 years ago

Hi Kevin, 
I was looking for the file for the contact form because I would like to add additional fields to it. However there is only the contact-us.php, which does not contain such info for me to either duplicate fields and customise the form. Where should I look to change the form please?
If this is somehow not possible, is there a way to delete it and add one of my own somewhere? 
Your help/suggestions are appreciated…!
