Question

I have a simple example of jquery ui. Basicly i have to list of items, each one is sortable. And what i want to accomplish is the following:
cancel sorting of the same list. with an example, if I click over an element on position one on list one, then drag it to position 6, and dropped. I want to prevent that, but if i drop the element in list two, that is ok.

i don’t know how to specify, in order to fit my requeriments. ConnectWith seems not to be enough:

$("#sortable").sortable({
    connectWith: [$('#sortable2')]
});

$("#sortable2").sortable({
    connectWith: [$('#sortable')]
});

here is the example:

This may not be exactly what you are looking for, but you can bind to the receive and stop events (they trigger in that order). receive indicates that a list item was received from another list. When this is triggered, you can temporarily unblock sorting. stop attempts to block sorting at all times:

var blocksort = true;
//Using jQuery 1.6.4, but use `.on` when available
$("#sortable, #sortable2").bind('sortreceive', function () {
    blockSort = false;
}).bind('sortstop', function (e) {
    if (blockSort) {
        e.preventDefault();
    }
    blockSort = true;
});
