Rails spinoffs - Jul 2005 - Allowing drops on "empty" sortable

Hey folks,

On the Drag and Drop demo page in the Sortable Lists Demo section:
http://script.aculo.us/drag-and-drop

If you drag all of the items from the first list into the second list, 
it appears that you cannot drag a list item back into the first (now 
empty) list.

Is there a way to allow a Sortable that is empty of draggable items to 
accept dropped items?

Currently it''s not easy to do. You''d need to add a single
element on
top of all other elements in the sortable container, being only a  
droppable. This is something I want in one of the next releases.

Thomas,

Do you have a code sample of this in action? My attempts locally seem to 
have come up short.

Here is a snippet of what I''m using. I''ve tried adding
containment and
accept options to the Droppable, but no go for me. I''ve tried it with a
parent DIV with nested DIVs instead of LIs.

<table><tr><td>
<ul id="listOne">
<li id="oneSubOne" class="interiorLI">one
one</li>
<li id="oneSubTwo" class="interiorLI">one
two</li>
<li id="oneSubThree" class="interiorLI">onw
three</li>
</ul>
</td><td>
<ol id="listTwo">
<li id="placeHolderLI" >placeholder</li>
<li id="twoSubOne" class="interiorLI">two
one</li>
<li id="twoSubTwo" class="interiorLI">two
two</li>
<li id="twoSubTree" class="interiorLI">two
three</li>
</ol>
</td></tr></table>
<script type="text/javascript">
Sortable.create(''listOne'',  {constraint:'''',
only:''interiorLI'',
containment:["listOne","listTwo"]} );
Sortable.create(''listTwo'',{
constraint:'''',only:''interiorLI'',
containment: [''listOne'', ''listTwo'']} );
Droppables.add(''placeHolderLI'');
</script>




In case it matters, Im using the latest 1.0 files right now,a dn teh 1.3 
of Prototype.js file.
