Can I make the horizontal scrollbar always display



Hi @kevinyaoooooo!

At the moment, the Gantt has no such functionality.
As a workaround, you can overwrite the internal _resizeScrollbars method in order to prevent hiding not active scrollbars.

Assign it an empty function during the onGanttLayoutReady event.

After that, the scrollbars will always display.
Here is a sample, where you can see how to do it:

I can not guarantee that this method will work after updates of the gantt in the future.
