最简单的用法。

import { TreeSelect } from 'antd';
const TreeNode = TreeSelect.TreeNode;

const Demo = React.createClass({
  getInitialState() {
    return {
      value: '',
    };
  },
  onChange(value) {
    console.log(arguments);
    this.setState({ value });
  },
  render() {
    return (
      <TreeSelect style={{ width: 300 }}
        value={this.state.value}
        dropdownStyle={{ maxHeight: 400, overflow: 'auto' }}
        placeholder="请选择"
        allowClear
        treeDefaultExpandAll
        onChange={this.onChange}
      >
        <TreeNode value="parent 1" title="parent 1" key="0-1">
          <TreeNode value="parent 1-0" title="parent 1-0" key="0-1-1">
            <TreeNode value="leaf1" title="my leaf" key="random" />
            <TreeNode value="leaf2" title="your leaf" key="random1" />
          </TreeNode>
          <TreeNode value="parent 1-1" title="parent 1-1" key="random2">
            <TreeNode value="sss" title={<b style={{ color: '#08c' }}>sss</b>} key="random3" />
          </TreeNode>
        </TreeNode>
      </TreeSelect>
    );
  },
});

ReactDOM.render(<Demo />, mountNode);
