The tree navigator control provides an interface that forms a tree structure in place without taking up more space on the screen. An item can be expanded to reveal sub items, if any exist, and collapsed to hide the same.
Its customization functionality allows user to customize:
Tree navigator is enabled with keyboard navigation support to select, expand, collapse, and navigate through items.
Items can be organized across multiple levels in hierarchical order without taking much space, in such a way that clicking an item will replace the existing view with its defined view. Previous view can be restored back through header just by clicking the Back button in the header.
