[jQuery] Re: I can't understand how work with elemetnts

[Vic]

New problem is founded:
I replace list items in example above:

<ul class="class1">
<li class="selected">List 3 Item 1
  <ul class="class2">
    <li class="selected">List 3 Item 1</li>
    <li>List 3 Item 2</li>
    <li>List 3 Item 3</li>
  </ul>
</li>
<li>List 3 Item 2
  <ul class="class2">
    <li class="selected">List 3 Item 1</li>
    <li>List 3 Item 2</li>
    <li>List 3 Item 3</li>
  </ul>
</li>
<li>List 3 Item 3
  <ul class="class2">
    <li class="selected">List 3 Item 1</li>
    <li>List 3 Item 2</li>
    <li>List 3 Item 3</li>
  </ul>
</li>
</ul>

And now items are not appear. Does exists some filter to take only
fist level items?
