How do I create a signup form where everyone can see who has signed up?

I want to create a signup form with multiple slots, and then each person who goes to sign up will be able to see which slots are already taken.

We have some widgets that you can try:

https://widgets.jotform.com/widget/appointment_slots 

https://widgets.jotform.com/widget/ticket_purchases 

So, each slot or available item that is taken, will not be available for the next one who loads the form. Let us know if you need more help.

Thanks!
