title: jquery-sortable using behavior of a linkedlist
body: <p>I suspect I'm not looking at this issue in the right way so here goes.</p>
  
  <p>I have essentially a LinkedList of data on a web page (<a href="http://en.wikipedia.org/wiki/Linked_list" rel="nofollow noreferrer">http://en.wikipedia.org/wiki/Linked_list</a>) that I'd like to manipulate using traditional Linked List behavior (i.e. just updating the reference/id of the "next" object) for performance reasons.  </p>
  
  <p>Where this gets a bit tricky is I'd ideally like to use Jquery's sortable to do this.  Like the user would drag something up/down and I could just do an Ajax call to the server with the id of the object that moved and the new parent id of that object (and then behind the scenes I could figure out how to reconnect things..maybe need more data than that...).</p>
  
  <p>But every example I've seen where sortable is used they were sending the whole re-indexed list to the database to update which seems unnecessary to me.  With a linked list to change an element's "index" I only need to make 3 updates which depending on the size of the list could be a big performance savings. Anyone have an example of what I'm trying to do...am I too far in left field?</p>
