What to do? :slight_smile:

#2

Unfortunaetly this is a designed behavior.

#3

It’s wrong behavior. :slight_smile:
I found this solution: attach plugin jquery.mousewheel.js

gridElement.find(".dhx_grid-fixed-cols").mousewheel((event, delta) => {
	let obj = $(event.target).closest(".dhx_grid-content").find(".dhx_grid-body").get(0);
	obj.scrollTop = obj.scrollTop + (-120 * delta);
});
