Formstack Online Forms

I'm not sure wrapping if this is just this version or all versions, but wrapping your site in an iframe doesn't constitute as a functioning plugin. 
Doesn't work on WP 4.5 as far as i'm concerned.



This doesn't work at all

This plugin allows you to easily embed Web forms built with Formstack's online form builder into your sidebar, pages, and posts.
