<ul id="test-list">
  <li id="listItem_10">first<img align="middle" src="Themes/arrow.png" class="handle" /></li>
  <li id="listItem_8">second<img align="middle" src="Themes/arrow.png" class="handle" />
    <ul id="test-sub">
      <li id="listItem_4><img align="middle" src="Themes/arrow.png" class="handle2" /></li>
      <li id="listItem_3"><img align="middle" src="Themes/arrow.png" class="handle2" /></li>
        <ul id="test-sub">
          <li id="listItem_9"><img align="middle" src="Themes/arrow.png" class="handle2" /></li>
        </ul>
      </li>
    </ul>
  </li>
</ul>

the problems i have:

1. sorting the main ul is working but not all the time - i will try to fix that my own but if there is a problem with the code here and not the one in proccess-sortable - tell me.
2. moving li in the main ul is ok but the sub or the sub of the sub is having problem - i can drag something from one sub to it's sub or the other way too - i don't want that to happend.
3. i want to be able to drag li and by selecting that one that only this ul group will send to proccess-sortable to be updated - how can i catch the specific ul of li i am draging?
