Extended Example

This form extends the basic example by radio buttons and select fields as well as a custom subject. It validates a non-required field, too. For the email body the uniform-email-table snippet provided by this repo is used. For the HTML snippet to work, a html-mail email service is used that is not provided by this repo.

When the form is sent, a copy of the email will be sent to me-too@example.com, as well as to the sender of the form if they checked the _receive_copy checkbox (but only once since we set the receive-copy property to false for the second email action).
