title: React select check on key down event whether menu is open or closed
body: <p>I am using <strong>react-select</strong> in my project for the select elements.</p>
  <p>I wonder if there is a way to check on keydown event in the select (can be both the select input or on the menu) if the menu is open or closed.</p>
  <p>I am using react select version ^2.4.2, and have to support explorer.</p>
  <p>P.S: for whoever is not familiar with the react-select library: it doesnt create typical HTML 'select' and 'option' elements, but rather a text input and on each click (or some dedicated keydown events (accessibility)) on the input/menu - it toggles a div with the options.</p>
  <p>Thank you!</p>
