title: react-select cannot set id
body: <p>Have a react-select component and the id field does not get set?  Is it possible to set an id?</p>
  
  <pre><code>&lt;Select
      id={field}
      className="reqform-project-dropdown"
      {...f.props(field)}
      disabled={
          readOnly ||
          onEdit ||
          f.props(field).read_only
      }
      clearable={false}
      options={this.props.common.tests}
      onChange={this.handleProjChange.bind(this, field,
          f.props(field).multiple,
          'test_req_unique_prefix')}
      labelKey="test_name"
      valueKey="test_req_unique_prefix"
  /&gt;
  </code></pre>
  
  <p>I have resorted to setting the id of the parent div, but it seems silly I can't do it directly for the select.</p>
