Is it possible to call another fancybox from an opened fancybox WITHOUT the opened fancybox closing?

Answer 1

On the parent page, setup fancybox using an iFrame:

$(document).ready(function() {

$(".fancybox").fancybox(

{

    width:'75%',

    height:'75%',

    'type' : 'iframe'

});

});

Inside the child page, put in your content, ensure it has a valid doctype, import the javascript and css that Fancybox needs again, and then declare your new Fancybox link. It may helps you
