I am wondering if I can create a question with unique options

I am wondering if I can create a question with unique options (once one is taken it would no longer be available).  I want to create time slots for folks to choose

You have to configure the time slots using our widget that would allow you to set limits on each item.

Example, our Ticket Purchases widget: https://widgets.jotform.com/widget/ticket_purchases.

We also have the following similar widgets:

To add a widget in your form, please follow the steps in the guide here https://www.jotform.com/help/252-How-to-Add-a-Widget-to-your-Form.

If you'd like to integrate the form with a payment from the selected time slots, please follow our method in the guide below:
