const STYLE = `

function getTreeData() {
    // big-data: generateData(1000, 3, 2)
    return [
      {
        key: '0',
        title: 'node 0',
        children: [
          { key: '0-0', title: 'node 0-0' },

        children: [

                title: 'node 1-0-1',
                children: [
                  { key: '1-0-1-0', title: 'node 1-0-1-0' },

            ],
          },
        ],
      },
    ];
  }
const defaultExpandedKeys = ['0', '0-2', '0-9-2'];

代码语言：javascript复制

 <style dangerouslySetInnerHTML={{ __html: STYLE }} />
                <Tree
                    defaultExpandAll={true}
                    defaultExpandedKeys={defaultExpandedKeys}
                    motion={motion}
                    treeData={getTreeData()}
                />
            </div>

务必引入样式

代码语言：javascript复制

import Tree from 'rc-tree';
import "rc-tree/assets/index.css"
