Thank you for contacting Syncfusion support.
Based on the provided information, we have checked your requirement “Is it possible to drag and drop scheduler” and it can be achieved in schedule. As default drag and drop feature has been enabled, you can just select an appointment and drag & drop to anywhere in the slots. We have prepared a simple sample for the same.
Kindly revert us if you have any concern.
