title: Select2.js with multiple tags and not dropdown icon?
body: <p>In Select2.js, by default there is a select dropdown box and a dropdown icon to make it intuitive for the user that it is a dropdown and not just an input box.</p>
  
  <p>When we make the select dropdown box with multiple tags enabled, the dropdown box looks more like an input text box. basically the dropdown icon is missing.</p>
  
  <p>Please refer - <a href="https://select2.github.io/examples.html" rel="nofollow">https://select2.github.io/examples.html</a></p>
  
  <p>So to add the dropdown icon, i could add it in the select2.js file. But i think it is not a good idea. Any other easier or better way to get the dropdown icon for multi - select select2 js dropdown box?</p>
