title: Show/hide fields depending on select value
body: <p>I am trying to show and hide a few form fields depending on the value of one of my select fields. I am looking to use arrays to hold what should be shown and what should not be shown for each select value, to save me from a massive switch statement, but cannot figure out how to do it.  </p>
  
  <p>I am using PHP and jQuery. Any help would be great.</p>
