Creating an attendance form that shows slots availability

I have an RSVP form where the participant can select which session they attend, but spaces are limited.  is there a way to show how many spaces are left or eliminate the option once registrations have maxed for that session?

You can try this Appointment Slots widget. Please check my demo form that I've created using the Appointment Slots widget:

Here is my screen capture of the demo form:

As you can see it is updating every time someone makes a reservation.

Hope that helps. Thank you!
