The Ordering Process - Modifications to item-initial.html

The item-initial.html file needs one tiny piece of JavaScript code added to it.


New or modified code is displayed in bold text.



top.myOrderList.itemsVisible = true;






The code that we added sets the myOrderList.itemsVisible flag to false, so that if the customer presses the "Clear" button, the myOrderList.clear method will not attempt to uncheck a group of checkboxes that do not exist.
