title: Check if drop-down has more than 1 option
body: <p>I have a drop down which is being populated on change of some other checkboxes, so on load the drop-down is empty(has only 1 option "Select" in it).</p>
  
  <pre><code>&lt;select id="A" aria-invalid="false"&gt;
      &lt;option disabled="" value="0"&gt;Select&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>On check of check-box the value will be added to a drop-down and on un-check of a check-box value will be removed from the drop-down.</p>
  
  <p>I have written a logic for that already. What I am looking for is how do I check if dropdown has any options added to it. ie. on check of a check box I want to display the dropbox if that's the first option added to it else hide the drop-down.</p>
