property	description

treeData	The tree source when using DataMap
initialTreeData	Fallback root data for DataMap when treeData is empty

parentId	The key name of parent id
dataType	The type of data source

Notes

• DataType.DataList: set listData and initialListData.
• DataType.DataMap: treeData has higher priority; when treeData is empty, initialTreeData is used as fallback root data.
• Multi-select onChecked returns checked leaf nodes after deduplication/filtering, not every checked parent node.
• Config.value is reserved for compatibility and is not part of current select-state calculation.
