You could use http://www.jstree.com/ - it's based on JQuery and has multiple call backs for drag/drop extensibilty. It shouldn't be too hard to connect up to a rails app.

I've managed to set up acts_as_tree, that's working fine. I also found a good php tutorial, that I've managed to get working in php.

Now I'm trying to port this over to ruby but I'm facing a problem. I have to get some data using a post request, but I'm not able to get it.

I've pasted my code in pastie : http://pastie.org/private/laeycedthniwwkkdhixjcg

This is the line I'm talking about, $updateRecordsArray = $this->input->post('recordsArray');

Could someone tell me how I can get the recordsArray (post request)?

The tutorial can be found at http://www.webresourcesdepot.com/dynamic-dragn-drop-with-jquery-and-php/

Or is there another way to do this? Thanks
