title: Why isn't Form.Select recognized in my simple react-bootstrap app, following the react-bootstrap documentation?
body: <p>I am a &quot;react-bootstrap with hooks&quot; first-timer and I am creating a simple form.  I am following the react-bootstrap documentation's example and I am running into a problem with select/option form elements.  Regular text input fields render normally without an error. Select statements seem to blow things up.</p>
  <p>Here is my code:</p>
  <pre><code>import { Form, Button } from &quot;react-bootstrap&quot;;
  
  export default function FormComponentName(props) {
      return (
          &lt;&gt;
              &lt;h1&gt;Search Form&lt;/h1&gt;
  
              &lt;Form&gt;
  
                  &lt;Form.Group className=&quot;mb-3&quot; controlId=&quot;searchState&quot;&gt;
                      &lt;Form.Label&gt;State&lt;/Form.Label&gt;
                      &lt;Form.Select defaultValue=&quot;State...&quot;&gt;
                          &lt;option&gt;State...&lt;/option&gt;
                          &lt;option value=&quot;1&quot;&gt;One&lt;/option&gt;
                          &lt;option value=&quot;2&quot;&gt;Two&lt;/option&gt;
                          &lt;option value=&quot;3&quot;&gt;Three&lt;/option&gt;
                      &lt;/Form.Select&gt;
                  &lt;/Form.Group&gt;
                 &lt;Button variant=&quot;primary&quot; type=&quot;submit&quot;&gt;
                      Search Data
                  &lt;/Button&gt;
  
              &lt;/Form&gt;
  
  
          &lt;/&gt;
      )
  
  }

  <p>Here is the yarn error message:</p>
  <pre><code>Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
  
  Check the render method of `FormComponentName`.

  <p>And from the console:</p>

  <p>Do I need to install an additional module, or is it something more obvious?</p>
