Hi, I was trying to use the DatePicker Application inside a Modal Box Application. The problem is that the DatePicker pop-up appears behind the modal box. I try to use the zindex property. But it doesn't work. This is the code I am using: afterLoad: function() { var dpicker = new DatePicker({relative : 'fieldName', language : 'us', zindex: '3000'});} Regards, Abel
