By default forms output a thank you message when submitted. however, if you would like a more catered experience for the visitors that complete your form you can set up a form redirect.
On the edit panel, at the very bottom is a section that will allow you to insert a url you would like your visitors to visit after a form submission.
You can include a static url such as www.boingnet.com or you can dynamically output a pURL by including the pURL url in the url string like so…
(Note: in order to use a customized pURL like the one above you will need to create a microsite with a specific “thank-you” page)
After you have specific the URL you would like your visitors to be redirected too you can click the insert button. This will insert a small html tag in your content that will control the redirect process.
