/**************************************************************************************

The below code provides the ability to turn any element on a page into a select option.
Essentially you have created a hidden form with a clean display.

Ex. You have an html table display records in the database. Each TR is a record with a
unique id. When you click on a row, the row highlighting is toggled and its id is
added/removing from a hidden select. Ctrl+click will allow the toggling and
adding/removing of multiple rows. Basically you have just turned the entire table into
a big select box.

The highlighting/unhighlighting css can be customized by overriding the class name.

Sample Script:

<link rel="stylesheet" type="text/css" href="{LINK_ROOT}/css/default.css">
<script type="text/javascript" src="{LINK_ROOT}/js/form_library_adv.js"></script>
<script type="text/javascript">
  var new_select = new customSelect();

  //override default css
  new_select.highlightClassName = 'hi';
  new_select.unhighlightClassName = 'low';
</script>

<style type="text/css">
//custom css
.hi { color : red; font-weight: bold; background-color: black;}
.low { color: black; font-weight: normal; background-color: white; }

</style>

<!-- The select object can be visible or hidden, if it is visible it should be disabled -->
<select name="ids[]" id="ids[]" multiple disabled></select>

<table width="100%">
   <tr id="1" onclick="new_select.customToggleSelect(this.id, event, 'ids[]');"><td> 1 </td></tr>
   <tr id="2" onclick="new_select.customToggleSelect(this.id, event, 'ids[]');"><td> 2 </td></tr>
   <tr id="3" onclick="new_select.customToggleSelect(this.id, event, 'ids[]');"><td> 3 </td></tr>
</table>
