The menu consists of all first level pages. But I need it to allso contain all second level subpages (if any) to the first level pages. The subpages I need to wrap in a nestet ul. I have tried for some time now, and I just cant get it right. What am I missing to make it work.
The solution Im working on is: www.intermail.dk/admin -> Lettershop Mailservice 2010.
The template Im working on is located in Templates -> Navigation and is called LIClean_new.xslt

A visible example of what Im trying to do is:
<ul>
  <li>Forside</li>
    <ul>
      <li>subpage 1</li>
      <li>subpage 2</li>
      <li>subpage 3</li>
    </ul>
  <li>Produkter</li>
    <ul>
      <li>subpage 1</li>
      <li>subpage 2</li>
      <li>subpage 3</li>
    </ul>
.....
</ul>
