You can set a Nintex form to go to a new blank form when the previous form is submitted. This is usually used for short forms where people need to submit multiple forms all at the same time. You can set this up by using the Form Settings > Advanced > Redirect URL field.
1. Click on the form Settings option on the Nintex Forms Designer ribbon, expand the advanced section, and type in NewForm.aspx for Redirect URL:
2. Save the form settings
3. I would recommend to also add a label at the bottom of the form notifying people what will happen when they submit the form. I’ve seen instances where people re-enter the same information because they didn’t realize the form actually submitted. So for example maybe create a label control like this:
4. Publish the form. Now when people Submit the form, a new blank form will open.
