Do you have Nation Builder integration for forms?

I don't think we have, but if you want to embed the form to Nation Builder, I'm sure that is possible as quoted from this article from their support page:

You need to embed your form using our iframe method: http://www.jotform.com/help/148-Getting-the-Form-iFrame-Code. 

Thanks
