We are sorry for the delay with the answer.
There is no native support for auto-scroll in scrollview. However, it is possible to add custom handlers to Kanban to implement it.
To track kanban DND, please, use events onListBeforeDragIn and onListDragOut that fires before a dragged element is released over the droppable area.
Comparing the x coordinate (left and right) of the dragging element with the x coordinate of the view, estimates the necessity and possibility to scroll the view.
