14.2.11.1.2. Feedback Form Submission

To determine what happens after someone submits feedback, you must go to Settings and Feedback Setup in the sidebar and select Submissions.
To set up a redirect web page, you must enter the link in the Redirect URL field.

Alternatively, you can customize the appearance of the submission page using HTML (for the body) and CSS (for styles). To do it in this way, scroll down to locate these customization fields and add your code.
Finally, press Save and Publish.
