block drag_resize move up and down functionality

when i resize the event horizontal direction it increase and decrease the event time fine.
but problem is when i drag the event up and down with resize functionality when drag the dotted left and right lines of event by moving up and down.even if i have block the event draging option false (scheduler.config.drag_move = false).

how i can stop the dragging of event up and down by moving resize dotted left and right lines of event movement.

Hi,
this is a default behavior and there is no public config to stop it. Although, you can override one of private methods to stop dragging if scheduler is in ‘resize’ mode. Please check the snippet
