I made a slight modification, namespacing the click event (so it can be unbound unambiguously) and unbinding it before reapplying.

I have checkboxes in drag-and-drop sortables. This way, I can re-apply enableCheckboxRangeSelection after sorting to get the order right.

I am really happy with the result I have so far though. Just discovered I could use tags to sync with the checkboxes and enable the entire row to be shift-clickable.

I could even get rid of the checkboxes visually by hiding them behind other divs or using position:absolute and left:-10000px

This is a great plugin and thanks for the great support!

IE6 loses the state of most form fields when the element is cloned. I would bet you might have to do something more complex to actually move the nodes other than the sort code you have above, but before implementing any more code I'd make sure you test the latest version of jQuery.

You can bind multiple listeners for a single event.

I am using this for sort plugins:
jQuery.fn.sort = function()
{
return this.pushStack([].sort.apply(this,arguments), []);
}

I realized something odd. Firefox and IE7 does cache the checkboxes, just IE6 does not. Anyways, that is good enough. It pretty much works well enough.

Another question if I may. In Gmail, I noticed that the background container gets highlighted when someone clicks a checkbox. Could you possibly point me in the right direction how to link the action of shift-clicking a checkbox and binding another object action?

Thank you,

How does your sort work? It might be the only option if they're getting unchecked because they're being removed from the DOM and then reinserted (which will clear them). You could cache the checked checkboxes, sort, and then recheck them, I suppose.
