Components	Data Entry	TreeSelect

Tree selection control.

When To Use

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.

TreeNode props

We recommend you to use treeData rather than TreeNode, to avoid the trouble of manual construction.
