Horizontal Scrolling in angularjs dragula.

[ghost]

Hi,
I am using angularjs dragula and I am not able to auto scroll to the overflow container that is hidden from the screen.

This is my issue:
I have five containers in my dragula and the 5th container is hidden from the screen. Now I want to drag an element from the first container and drop it in the 5th container. But I am not able to do this, since the screen is not auto scrolling to the 5th container

Does angularjs-dragula support vertical scrolling? or is there a property that I'm missing.
Can I get some help with this.?
