Jquery Drag and Drop to create menu (similar to wordpress custom menus)

[eluser]Dan Tdr[/eluser]
Hello,

I want to create a similar effect to the one in the custom menu in wordpress 3.0+
What i want:
I want to be able to create a custom menu via drag and drop (with or without sub elements)
I need to have all my pages in a list and be able to add them and order them via drag and drop

I found: http://papermashup.com/drag-drop-with-php-jquery/ a great sorting via drag and drop tutorial(with files included) but it does not allow me to add new elements or remove any of them.
I found a little more and i found: http://tutorialzine.com/2009/09/shopping...hp-jquery/ but again this one lets me add and remove items but does not let me sort them the way i need.

Once added, the element should be removed from the list and show only in the menu.

I was wandering if anyone can point me into the right direction, or help in any way, or maybe someone already did this kind of thing or has an idea of how it should be.

Thank you,
Dan
