title: How to autofocus an input field in semantic-ui-react?
body: <p>I'm having a difficult time autofocusing an input field with semantic-ui-react. The <a href="https://react.semantic-ui.com/elements/input" rel="noreferrer">documentation</a> doesn't seem to include an <code>autoFocus</code> prop and the <code>focus</code> prop doesn't place the cursor inside the input field as would be expected.</p>
  
  <pre><code>&lt;Form onSubmit={this.handleFormSubmit}&gt;
    &lt;Form.Field&gt;
      &lt;Form.Input
        onChange={e =&gt; this.setState({ username: e.target.value })}
        placeholder='Enter your username'
        fluid /&gt;
    &lt;/Form.Field&gt;
  &lt;/Form&gt;
  </code></pre>
  
  <p><strong>EDIT: This code works:</strong></p>
  
  <pre><code>&lt;Form onSubmit={this.handleFormSubmit}&gt;
    &lt;Form.Input
      onChange={e =&gt; this.setState({ username: e.target.value })}
      placeholder="Enter your username"
      autoFocus
      fluid /&gt;
  &lt;/Form&gt;
  </code></pre>
