I have been trying to do this all day. At the end i managed to get it working. I know it is not the best way to do.

Can someone please show me a better way. I need 12 altogether. It does not need to be check box either. It can be just a text. I got the idea from com/2006/12/14/using-jquery-to-show-hide-form-elements-based-on-a-checkbox-selection/

I managed to upload it on http://utilitybase.com/paste/wmq

    If I got you right, you might play around with

    <head>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" type="text/javascript"></script>
  <script type="text/javascript">
    $(document).ready(function(){
      var prototype = $('.prototype').clone();

      $('.prototype > input[type="checkbox"]').live('click', function() {
        if($(this).is(':checked')) {
          var clone = prototype.clone();
          clone.find('input[type="checkbox"]').attr('checked', false);
          $(this).parent('.prototype').append(clone);
        } else {
          $(this).parent('.prototype').find('.prototype:last').remove();
        }
      });
    });
  </script>
</head>

<body>
  <form>
    <div class="prototype">
      <input type="text" name="" maxlength="30" />
      <label for="checkbox"> Check to enter another email address:</label>
      <input id="checkme" type="checkbox" />
    </div>
  </form>
</body>
</html>

    EDIT: This add’s a new input/label/checkbox prototype inside the current one or removes it’s children on the other hand. You could add ids to the fields as well.
