Hi Laurin,
Greetings from Syncfusion Support..!
We have checked the possibility at our end based on your shared query “search for free time slots”, but regret to let you know this is not feasible with our Scheduler’s current architecture.
But in the meantime, you can restrict the users to create and update more than one appointment on specific time slots. Also, you can disable the CRUD action on those time slots if it is already occupied, which can be achieved using Scheduler’s public method isSlotAvailable. And for further reference, kindly refer to the below UG link.
Kindly try the above UG link and if this does not meet your requirement please share with us more details like use case scenario, images/video demo with clear steps. We are waiting to help you better once you shared more details about your requirement.
Regards,
Hareesh
