Can I book an appointment with GravityCalendar?
Short answer: Unfortunately, no.
Long answer: GravityCalendar doesn't have any booking functionalities. Our add-on is similar to a GravityView View layout; it allows you to display your form submissions on the front end in a calendar format by using a date field on your form.

We recommend using Gravity Forms Inventory by Gravity Wiz in conjunction with GravityCalendar if you need to create a booking system based on available dates.
