title: Set focus in input on clicking div
body: <p>I have the following HTML inside function component</p>
  <pre><code>&lt;div&gt;
     &lt;input /&gt;
  &lt;div&gt;
  &lt;div&gt;
     &lt;input /&gt;
  &lt;div&gt;
  &lt;div&gt;
     &lt;input /&gt;
  &lt;div&gt;
  </code></pre>
  <p>I am not finding any easy way to do this...</p>
  <p>I have gone some article saying to store input ref, but here I have confusion about how to store <code>inputref</code> using id or something...</p>
  <p>I am totally lost so unable to proceed</p>
  <p>Please help</p>
  <p>Thanks</p>
