I have now tryed to figure this out for a couple of hours. I was up to this point sure that the problems was only my own stupiditys fault, but now I'm not that sure anymore.

The first problem I encountered was that when a element is being dragged in a sortable list(all semantic and stuff), it looses it's css styles inherited by parent elements. I figured out I have to style it by a class in the element(or the id). Not that this is a bug, but it would be very nice to see a solution to that. (Altough I understand that might be hard.)

The 2. problem I got was that if an <UL> contains both "accepted" sortable elements, and elements not accepted, it becomes impossible to place a sortable element just above the unaccepted element. This results in haveing to move the element above the element over the unaccepted, for then to move the element just above the unaccepted one step up. A solution shouldn't be too far away i guess(and hope).

The third problem is that if I set "containment: 'parent'", I suddenly cant move the elements down on the list, only up. I don't know if thats because of some "css tecnical mambo jambo mess ups", but it's surtently not user friendly.

Fourth problem is about ghosting. And let me give you this, the function realy "ghosts" the element after it's dropped! In other words: The element being dropped disappers!

Another tips(or something like that): The possiblity to wrap the sortable elements in different elements to make an multidimentional array of some kind. Some thing like this:

<ul>
   <li id='installed'>
      <ul>
         <li class='sortable'>Installed Item #1</li>
         <li class='sortable'>Installed Item #2</li>
         <li class='sortable'>Installed Item #3</li>
      </ul>
   </li>
   <li id='not-installed'>
      <ul>
         <li class='sortable'>Not-Installed Item #1</li>
         <li class='sortable'>Not-Installed Item #2</li>
      </ul>
   </li>
</ul>

Would result in something like this:

data = {
      installed = {
            item-in-installed #1
            item-in-installed #2
            item-in-installed #3
      }
      not-installed = {
            item-in-not-installed #1
            item-in-not-installed #2
      }
}

I guess you catch the point.

I haven't had the time to check deeply into the result of the sortable, so I'm not sure if this allready exists, but surely I could use it!

Other then that I haven't found any more bug/problems I can remember. So then it's just one more thing to say:

I love jQuery, so far I have had the chance to test it, and the interface plugin is adorable! Keep up the good work! This is quality!

(NB: Many of these bug/problems might be my lack of skills in js/jQuery, and shoot me if thats the case. Anyway, I hope I have contributed with something usefull. I also attach the file(with styles) I have used, so you guys can compare with my script.)

(NBNB: I'm a php-programmer if that helps you in any way, alltough I haven't used any php-code in this case.)
