| 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, label, children, [disabled, disableCheckbox, selectable] }> | \[] |
| treeDataSimpleMode | Enable simple mode of treeData.(treeData should like this: [{id:1, pId:0, value:'1', label:"test1",...},...], pId is parent node's id) | false\|Array<{ id: string, pId: string, rootPId: null }> | 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] }> | \[] |
| treeDataSimpleMode | Enable simple mode of treeData. Changes the `treeData` schema to: \[{id:1, pId:0, value:'1', title:"test1",...},...] where pId is parent node's id). It is possible to replace the default `id` and `pId` keys by providing object to `treeDataSimpleMode` | false\|object\<{ id: string, pId: string, rootPId: null }> | false |
| treeDefaultExpandAll | Whether to expand all treeNodes by default | boolean | false |
