How do I limit user to book one slot per choice?

I want to allow the user to make a choice (like pick a seat) and if they complete the form, remove that seat or flag it as reserved in future forms.   Can the tools do this and if so, which one?

You can use our Appointment Slots widget:

The only widgets we have that can do something similar to what you need are:

This widget is perfect for showing your form users what times are available for an appointment. Not only that, you can limit how many people choose an available slot because the widget reduces the number of selected slots each time the form is submitted.

Let us know if you have further questions.

Thanks.
