I would like to know if it is possible to allow events to overlap for specific resources but not all, as I have not found anything about this in the documentation.
Just in case anybody stumbles over this problem or wants to achieve something similar I found this page (https://doc.daypilot.org/scheduler/event-moving-customization/) very helpful.
You can basically check the resources yourself and then forbid the move or resize, so that it is not executed.
Thanks for posting the solution!
