title: Disable entire form elements with respect to a state. React
body: <p>I am disabling the inputs using the <code>isFetching</code> prop, 
  but this is getting reduntant as I have to keep this in every input field.
  Is there a way to disable the entire form?
  Like a <code>disable</code> property in <code>&lt;form&gt;</code> tag or something?</p>
  
  <pre><code>&lt;form&gt;
    &lt;input type="text" disabled={this.props.isFetching} /&gt;
    &lt;input type="text" disabled={this.props.isFetching} /&gt;
  &lt;/form&gt;
  </code></pre>
