The extension adds a vertical automatic scrolling to a Vaadin Grid or Vaadin TreeGrid component. When a drag is in progress and the user drags the mouse cursor to the top or bottom of the Grid, the grid will start to automatically scroll. By its nature the extension should work with any Grid or TreeGrid as long as additional customisations are not needed on the GridDragSource and/or GridDropTarget extensions. As a part of the extension the badge showing the number of rows being dragged is also updated to contain the actual count of selected rows (not just the visible ones) and the DragStartEvent has been modified to contain the full list of dragged rows (including non-visible rows). ### Vaadin Pro This component is available in the Vaadin Pro subscription. It is still open source, but you need to have a valid CVAL license in order to use it. Read more at: [Pricing](https://vaadin.com/pricing)
