Display who submitted form

We are trying to auto-populate who has submitted this endorsement form:
https://www.gallatinpartners.org/endorsements/

An example of another site using Ninja Forms:
http://healthyriversmt.org/endorsements/

…they are auto-populating a widget below with the names of anyone that submits/endorses their cause via the form.

Is this an option with Contact Form 7?
