/*

CUSTOM FORM ELEMENTS

Created by Ryan Fait
www.ryanfait.com

The only thing you need to change in this file is the following
variables: checkboxHeight, radioHeight and selectWidth.

Replace the first two numbers with the height of the checkbox and
radio button. The actual height of both the checkbox and radio
images should be 4 times the height of these two variables. The
selectWidth value should be the width of your select list image.

You may need to adjust your images a bit if there is a slight
vertical movement during the different stages of the button
activation.

This script was edited by Drew Glaser. Changes:
-- Added support input elements with multiple class names (originally 
   you could only have class="styled")
-- Added support for labels. You must give the label a class name: 
   "customLabel". This is so the script knows to shut off the normal
   functionality of the label. You also need to pass in:
   onClick="Custom.checkLabel('INPUT ID');"
   to the label.

   example:
   <input type="checkbox" name="1" id="1" value="1" class="itemCheckbox styled">
   <label for="1" class="customLabel" onClick="Custom.checkLabel('1');">label.. </label>
*/

var checkboxHeight = "32";
var radioHeight = "23";
var selectWidth = "190";
var groups = [
	'_popular',
	'_newsletter_newsletter',

	'_resource_ministry',
