How to have limited spots in form and once a user picks a spot, availability should automatically reduce?

One last feature that we are looking for is on that we can list available spots in a class, say 10 and as people go in and choose the class, then pay, the availability will automatically reduce as people purchase spots.  Can JotForm handle this type of traffic?  Thank you!

Hello Tiffany,

Yes it is possible to achieve your requirement by adding any of the following widgets in form:

Gift Registry

Quantity Gift Registry

Once a user selects any item form any of the above widget and submits form, the available quantity will automatically be reduced. 

Hope this helps.

Do try it out and get back to us if you have any questions.

Thank you!
