title: ANTD onFocus is not called every time while i open the select options
body: <blockquote>
  <p>onFocus   Called when focus</p>
  </blockquote>
  <p>Here, I am using <a href="https://ant.design/components/select/" rel="nofollow noreferrer">antd</a> select Where i am using <strong>onFocus</strong> props which should actually be called whenever i clicked or open the select options. But it's not being called every time. What's the issue?</p>
  <p>Actually i do have lot of select boxes in my project and i am using the same select box so whenever i focus the select boxes am fetching the particular selectbox options.</p>
  <p>But since onFocus is not being called everytime I am facing issue.</p>

  <p>onClick is not supported by Select. But the thing i needed is like onclick event so that everytime i click select box i want to fetch the data.</p>
