title: Show Additional <div> if Variable Equals This or This
body: <p>I have a simple forms site where I need to show an additional  only if the department selected is one of three --- Engineering, IT, or Product. The below function works, but I am only able to list one department. It does nothing if I put all three in one set of quotes or in comma-separated individual sets of quotes. Is there a better function to accomplish this?</p>
  <pre><code>$(&quot;#department&quot;).change(function() {
      if ($(&quot;#department&quot;).val() == &quot;IT&quot; || $(&quot;#department&quot;).val () == &quot;Modify&quot;) {
          $(&quot;#level&quot;).show();
      } else {
          $(&quot;#level&quot;).hide();
      }
  });
  </code></pre>
