Use form rules if you want to redirect to different web pages based on user input. Establish the condition and paste the URL. You can add as many redirect possibilities as necessary. You can also redirect users to a certain webpage based on the language they have selected on the form (if the feature is enabled). You’ll find the enabled languages of your form included in the condition’s dropdown list of your rule. To learn more about translations, follow our documentation here.
If you want the redirect to behave in a certain manner (e.g. redirect form visitors in a new frame), you must go the Notifications → Form User Option section, under Thank You Page and Redirects, just as you would have if you wanted to redirect all form visitors to the same web page. In Thank You Page and Redirects, enable any of the two options and use the dropdown to select how you want the redirect to behave (e.g. select in new frame (if browser allows it)). Press Save and switch back to the previous option. Hit Save again and you are done.
