|
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.

|
|
value | To set the current selected treeNode(s). | __Default:__ string\|string[]. __With `labelInValue` set:__ { value: string, label: ReactNode }/Array<{ value: string, label: ReactNode }>. __With `treeCheckStrictly` set(`halfChecked` is set to `false`):__ { value: string, label: ReactNode, halfChecked: string[] }/Array<{ value: string, label: ReactNode, halfChecked: string[] }>. | -
|
|
labelInValue | Determine whether to put `label` into `value`, the type of `value` as specified in the above | boolean | false
|

defaultValue | To set the initial selected treeNode(s). | string\|string[] | -
|
|
multiple | Support multiple or not, will be `true` when enable `treeCheckable`. | boolean | false
|
|
onSelect | A callback function, can be executed when you select a treeNode. | function(value, node, extra) | -
|
|
onChange | A callback function, can be executed when selected treeNodes or input value change | function(value, label, extra) | -
|
|
allowClear | Whether allow clear | boolean | false
|
|
onSearch | A callback function, can be executed when the search input changes. | function(value: string) | -

|
|
showCheckedStrategy | __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
|
|
treeDefaultExpandAll | Whether to expand all treeNodes by default | boolean | false
|
|
treeDefaultExpandedKeys | Default expanded treeNodes | string[] | -
|
|
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 | boolean | false
|
|
filterTreeNode | Whether to filter treeNodes by input value. The value of `treeNodeFilterProp` is used for filtering by default. | boolean\|Function(inputValue: string, treeNode: TreeNode) (should return boolean) | Function
|
|
treeNodeFilterProp | Will be used for filtering if `filterTreeNode` returns true | string | 'value'
|
|
treeNodeLabelProp | Will render as content of select | string | 'title'
