I would like to close the modal by click outside,
how can I do?
edit the file /js/tygh/core.js
find the line 2391
w.find('.ui-dialog-titlebar-close').attr({'data-dismiss':'modal', 'type':'button'});
and add the code after
$(".ui-widget-overlay").click(function(){
$(".ui-dialog-titlebar-close").trigger('click');
});
