title: Clear Select Material UI with React State
body: <p>I´m tying to clear all Criteria's from some controls using <code>state</code> but having problems with the Select Material UI</p>
  <p>In the costructor</p>
  <pre><code>this.HandleclearFiters = this.HandleclearFiters.bind(this);
  </code></pre>
  <p>The Clear Handler for the Button</p>
  <pre><code> HandleclearFiters() {
      this.setState({
        startEmission: &quot;&quot;,
        endEmission: &quot;&quot;,
        startValidity: &quot;&quot;,
        endValidity: &quot;&quot;,
        participantFirstName: &quot;&quot;,
        participantLastName: &quot;&quot;,
        paticipantCertNumber: &quot;&quot;,
        selectYesNo: &quot;&quot;,
        selectLevel: &quot;&quot;
      });
    }
  </code></pre>
  <p>This works in a <code>&lt;TextField</code></p>
  <pre><code>&lt;TextField id=&quot;txtStartEmission&quot; 
  value={this.state.startEmission} 
  onChange={e =&gt; this.setState({ startEmission: e.target.value })}
  </code></pre>
  <p>This will not work on a <code>&lt;Select</code></p>
  <p>So I tried this workaround, not working also</p>
  <pre><code>&lt;Select
  labelId=&quot;selPrintedLabel&quot;
  id=&quot;selPrinted&quot;
  label=&quot;Printed&quot;
  fullWidth={true}
  variant=&quot;outlined&quot;
  defaultValue={this.state.selectYesNo}
  onChange={e =&gt; this.setState({ selectYesNo: typeof e.target.value === 'string' ? e.target.value : '' })}
  </code></pre>
  <p>Thank you for helping</p>
