How to enable the content editor as a droppable target with jQuery-ui?

In the above example the following line:

jQuery(".myDiv").find("li").each(function(){

should be:

jQuery(".keywords").find("li").each(function(){

That should enable the list items to be dragged and dropped.

To allow the items to be dropped on the TinyMCE textarea the following code works.

$('#editorcontainer').droppable({ 
    drop: function(event, ui) { 
        alert('dropped'); //NOW FIRES!
        //Dynamically add content
        tinyMCE.activeEditor.execCommand('mceInsertContent', false, 'New content.');
    } 
});
