Michelle Oliphant as you are still listening in this thread the correct answer is actually "Yes." You can hide the form based on segment, Segment the LP and wherever you want to hide the form, set the form to a placeholder form. Let's say form ID 999. Then just add CSS mktoForm_999 { display: none; }. That way, anybody who would see your placeholder instead sees nothing. Everybody else sees the form set for their segment.
Sanford Whiteman Well, blow me down. I remember trying for ages circa 2012 (I think) to segment a form and it didn't seem possible. That is good to see it's possible.
I didn't know it was either until I tried some stuff today... these challenges are really distracting!
Sanford Whiteman Don't let yourself get too distracted, remember you have some response-tracking tools to build!
