import { Select } from 'antd';
const Option = Select.Option;

      options = [];
    } else {
      options = ['gmail.com', '163.com', 'qq.com'].map(function(domain) {
        const email = value + '@' + domain;
        return <Option key={email}>{email}</Option>;
      });
    }
    this.setState({
      options: options
    });
  },
  render() {
    // filterOption 需要设置为 false，数据是动态设置的
    return <Select combobox
      style={{width:200}}
      onChange={this.handleChange}
      filterOption={false}
      searchPlaceholder="请输入账户名">
      {this.state.options}
    </Select>;

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