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.

| disabled | Disabled or not | boolean | false |  |
| dropdownClassName | The className of dropdown menu | string | - |  |
| dropdownMatchSelectWidth | Determine whether the dropdown menu and the select input are the same width. Default set `min-width` same as input. Will ignore when value less than select width. `false` will disable virtual scroll | boolean \| number | true |  |

| Name    | Description  | Version |
| ------- | ------------ | ------- |
| blur()  | Remove focus |         |
| focus() | Get focus    |         |
