 | 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` | boolean \| object<{ id: string, pId: string, rootPId: string }> | false |  |

 | treeCheckStrictly | `checkable` 状态下节点选择完全受控（父子节点选中状态不再关联），会使得 `labelInValue` 强制为 true | boolean | false |  |
