I am trying to show the dragging element but I am not able to. I can see outside of the Event calendar. I have customized scheduled events using renderScheduleEvent.
is it the cause that I am not able to see?
Hello @mazhar 
Could you please share some more details on the problem?
How does your code look like and what are the steps to reproduce?
Do you have any errors on the console?
If you can share a live link (in private message) which demonstrates the issue, that would also help.
