As the name suggests that a tree region is used to display objects in a hierarchical format. It segregates data into child/leaf nodes and parent nodes which can be either expanded or collapsed. The purpose of tree is to allow users to promptly browse through composite sets of hierarchical objects and access detailed information for a record by highlighting it in the tree. The visual representation of the hierarchy using the tree also depicts the relationship between objects with respect to one another.
