|
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.

|
|
| getPopupContainer | To set the container of the dropdown menu. The default is to create a `div` element in `body`, you can reset it to the scrolling area and make a relative reposition. [example](https://codepen.io/afc163/pen/zEjNOy?editors=0010) | Function(triggerNode) | () => document.body |

|
| maxTagCount | Max tag count to show | number | - |
|
|

|
| searchValue | work with `onSearch` to make search value controlled. | string | - |
|
|
| showCheckedStrategy | The way show selected item in box. **Default:** just show child nodes. **`TreeSelect.SHOW_ALL`:** show all checked treeNodes (include parent treeNode). **`TreeSelect.SHOW_PARENT`:** show checked treeNodes (just show parent treeNode). | enum { TreeSelect.SHOW_ALL, TreeSelect.SHOW_PARENT, TreeSelect.SHOW_CHILD } | TreeSelect.SHOW_CHILD |
|
|
| showSearch | Whether to display a search input in the dropdown menu(valid only in the single mode) | boolean | false |

|
| treeCheckable | Whether to show checkbox on the treeNodes | boolean | false |

|
| treeCheckStrictly | Whether to check nodes precisely (in the `checkable` mode), means parent and child nodes are not associated, and it will make `labelInValue` be true | boolean | false |
|
|
| treeData | Data of the treeNodes, manual construction work is no longer needed if this property has been set(ensure the Uniqueness of each value) | array<{ value, title, children, [disabled, disableCheckbox, selectable] }> | \[] |

|
|
| treeNodeLabelProp | Will render as content of select | string | 'title' |
|
|
| value | To set the current selected treeNode(s). | string\|string\[] | - |
|
|
| onChange | A callback function, can be executed when selected treeNodes or input value change | function(value, label, extra) | - |
|
|
| onSearch | A callback function, can be executed when the search input changes. | function(value: string) | - |
|
|
| onSelect | A callback function, can be executed when you select a treeNode. | function(value, node, extra) | - |
