jQuery UI sortable scroll helper element offset Firefox issue

Question

I have a problem with a jQuery UI 1.7.2 sortable list in Firefox 3.6, IE7-8 work fine. When I\'m scrolled down a bit, the helper element seems to have an offset of the same

Answer 1

If you want to prevent browser sniffing, the CSS only solution is to set the ul or a container style to overflow: auto. If you look at the source through firebug, it's the way jQuery does it in their example.

Answer 2

I "fixed" this using newer jQuery/jQuery UI versions.

• jQuery 1.8.0
• jQuery UI 1.8.23

Answer 3

I also had this problem and fixed it with the following code:

var wscrolltop = 0;
$sortable_elements.sortable({ 
    start: function(event, ui) {
        wscrolltop = $(window).scrollTop();
    },
    sort: function(event, ui) {                   
        ui.helper.css({'top' : ui.position.top + wscrolltop + 'px'});
    }
});

I discovered, that there still is a problem if you scroll with your sortable-element. Maybe somebody has a solution for this?

UPDATE: The fix is:

$sortable_elements.sortable({ 
    connectWith: '#personal-favs ul.fitems',
    sort: function(event, ui) {  
        ui.helper.css({'top' : ui.position.top + $(window).scrollTop() + 'px'});
    }
});

But still - if you're leaving the list, the sort-event seems to stop.
