onDragOver (item: ItemDataType, event) => void drag over 回调
onDragStart (item: ItemDataType, event) => void drag start 回调
onDrop (dropData: DropDataType, event) => void drop 回调
onExpand (expandItemValues: string[], item: ItemDataType, concat:(data, children) => Array) => void 树节点展示时的回调
onSelect (item: ItemDataType, value, event) => void 选择树节点后的回调函数
renderTreeIcon (item: ItemDataType) => ReactNode 自定义渲染 图标
renderTreeNode (item: ItemDataType) => ReactNode 自定义渲染 tree 节点
searchKeyword string (受控)搜索关键词
showIndentLine boolean 是否显示缩进线
value string 当前选中的值
valueKey string ('value') tree 数据结构 value 属性名称
virtualized boolean 是否开启虚拟列表


interface ItemDataType {
  /** The value of the option corresponds to the `valueKey` in the data. **/
  value: string;

  /** The content displayed by the option corresponds to the `labelKey` in the data. **/
  label: ReactNode;

   * The data of the child option corresponds to the `childrenKey` in the data.
   * Properties owned by tree structure components, such as TreePicker, Cascader.
  children?: ItemDataType[];

   * Properties of grouping functional components, such as CheckPicker, InputPicker
  groupBy?: string;

   * The children under the current node are loading.
   * Used for components that have cascading relationships and lazy loading of children. E.g. Cascader, MultiCascader
  loading?: boolean;


interface ListProps {
   * Size of a item in the direction being windowed.
  itemSize?: number | ((index: number) => number);

   * Scroll offset for initial render.
  initialScrollOffset?: number;

   * Called when the items rendered by the list change.
  onItemsRendered?: (props: ListOnItemsRenderedProps) => void;

   * Called when the list scroll positions changes, as a result of user scrolling or scroll-to method calls.
  onScroll?: (props: ListOnScrollProps) => void;


type DropDataType = {
  /** drag node data */
  dragNode: any;

  /** dropNode data */
  dropNode: any;

  /** node drop position */
  dropNodePosition: TREE_NODE_DROP_POSITION;

  /** Update Data when drop node */
  createUpdateDataFunction: (data: any[]) => any[];

  DRAG_OVER = 0, // drag node in tree node
  DRAG_OVER_TOP = 1, // drag node on tree node
  DRAG_OVER_BOTTOM = 2 // drag node under tree node


  • <CheckTree> 用于展示一个树结构数据,同时支持 Checkbox 选择。
  • <TreePicker> 选择器组件,树形单项选择器。
  • <CheckTreePicker> 选择器组件,在 TreePicker 节点上支持 Checkbox,用于多选 。
