Property

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.
