By adding the Raven Form element to your layout, you may want to redirect to a page after the form is submitted by a user. This could be easily done by adding a redirect action to the form.
1. In Elementor, drag and drop a Form widget into your layout so that a new panel will open on the left side of the Elementor with the element specific settings.
2. Go to Content tab and in the Settings section add a Redirect action.
3. A new Redirect options panel will emerge at the bottom of the Settings section. So you can define the page you want to redirect to.
4. Update the page.
