How do I add section headers to my form

As far as I know there isn't a built-in way to do this.

However, it is possible to extract the code from the Marketo Code, and then just use that whever you want to have the form. You will lose the progressive profiling but you gain a LOT more control over your forms, especially from a design perspective.

One of the speaker from Marketo Summit has this great page with a lot of tips/tricks for Marketo Forms:

Good luck!

There isn't a way to do it in the form builder, but if you have someone savvy with HTML, you can post the form on a blank page, copy the source code, and manipulate it however you'd like.

Here's an example - you can use the source code on this page as giudance: http://info.shipwire.com/referrals

Here's a community article explaining how to add form section headers using a bit of jQuery. https://community.marketo.com/MarketoArticle?id=kA050000000KysPCAS

No need to strip out the source and host outside a Marketo Landing page.

Hopefully this will be one of the updates in Forms 2.0 :)
