Hi Stefano,
It seems it’s not that simple. The minimal form has the label right inside the field so it does not take up extra line. Using the form will create different line for label as well as the field, so it ended up with 4 lines. It would be so much cleaner if the name and email are on the same line and the label are inside the fields. Can you not just have an option with the extra name field in front of the email? :p
Thanks.
