title: change selected value dropdown reactjs
body: <p>I'm using a dropdown box with ReactJS and I'm using the default values that I get from "this.state.whoIsChecked.allowDestroyAll". But when I use it as default value, I can't change the value anymore. Here follows the code I'm using:</p>
  
  <pre><code>&lt;select 
  className="form-control" 
  id="ada" 
  value={this.state.whoIsChecked.allowDestroyAll}&gt;
      &lt;option&gt;true&lt;/option&gt;
      &lt;option&gt;false&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
