If we use an embedded form, I know it doesn't auto populate the registrant's info. However, does remember the person (cookied) so essentially they don't have to fill out the same form again for each whitepaper?
Please move the question to Products and I'll answer it there. ("Community" refers to the Marketo Nation website, not to peer-to-peer support. And yes, this is confusing.)
Check the docs. Pretty sure Known HTML is on marketo pages only.
AFAIK, Known HTML works for embedded forms as well.
