Autoresponder emails, how to hide empty fields

Hi, 

How do I make it so unfilled form items will not be included on the autoresponder email, which serves as the clients receipt? Is there a code to add or some kind of setting I'm missing?

Thank you!

Unfilled form fields will automatically be omitted from emails using the default email.  It is not possible to omit empty fields if the notification or autoresponder has been edited.  Creating a new notification or autoresponder for your form will give a default email and will hide empty fields.

Thanks, David! So, if I use the default email and modify the look of it (colors, fonts, etc.) does that count as an "edit" that will prevent the empty fields from being omitted?

Colors, and fonts change will not break the default email, so the empty fields will still be hidden.
