Components	Data Entry	TreeSelect

Tree selection control.

TreeSelect is similar to Select, but the values are provided in a tree like structure. Any data whose entries are defined in a hierarchical manner is fit to use this control. Examples of such case may include a corporate hierarchy, a directory structure, and so on.
