Hi, Is it possible to set an area/time-span as the active drop-area, or alternatively, disable surrounding areas? I would like to only allow dropping events to specific days and times.
You can use the real-time event handlers to check custom conditions:
You can forbid the current target by setting args.allowed = false. This will forbid the drop action and it will also provide a visual hint to the user by changing the shadow color (by applying a custom css class).
See also a couple of examples here:
In addition to the changed color, you can also provide custom text using args.right.html.
