title: How to check selected option in react js
body: <p>I'm trying to add selected option in my select box using react js. here is my code</p>
  <pre><code>&lt;Field component='select' name='sample'&gt;
    &lt;option value={1}&gt;option1&lt;/option&gt;
    &lt;option value={2}&gt;option2&lt;/option&gt;
    &lt;option value={3} {... &quot;selected&quot;}&gt;option3&lt;/option&gt;
    &lt;option value={4}&gt;option4&lt;/option&gt;
    &lt;option value={5}&gt;option5&lt;/option&gt;
  &lt;/Field&gt;
  </code></pre>
  <p>I try already the defaultValue and also adding <code>selected</code> but it doesn't work. Did I miss something about my code?</p>
