If you want your participants to be able to double-check their information once they have confirmed their registration (for example on the registration confirmation Thank you page), you can do so by using the "Read-only form" also available in single column & two columns formats.
Simply add the read-only forms with the same fields the participants have previously filled in.
Once this page is published and connected to the correct workflow, the participants will be able to see these read-only fields with the details they have entered on the thank you page.
