title: Is it possible to open React-Select component as it mounts?
body: <p>Not just focusing, but to actually open the component and display options. 
  I know this isn't simple on a regular select component (see <a href="https://stackoverflow.com/questions/430237/is-it-possible-to-use-js-to-open-an-html-select-to-show-its-option-list">Is it possible to use JS to open an HTML select to show its option list?</a> ), but perhaps it is still possible with React-Select. </p>
