The TreeView Wrapper component provides the autoScroll property that allows the out-of-the-box scrolling of component items when performing drag-and-drop operations.
Please provide the autoScroll property inside the Native TreeView component.
The current implementation of the Native TreeView doesn't allow you to customize the expand/collapse arrows of the component.
Can you please provide a property that allows the definition of a custom class for a given TreeView group? Being able to define such a class, using CSS we can easily control the look of the different elements of each TreeView group.
