Nested menu

I created this xslt to render a nested menu like this, the nice part is that it always starts with the parent at level 3 (even if you are at a deeper level).

      <h2>Basic Elements</h2>

      <ul class="level-1">

        <li>

          <a href="/internet/basic-elements/logo">Logo</a>

          <ul class="level-2">

            <li>

              <a href="/internet/basic-elements/logo/download-logo">Download logo</a>

            </li>

          </ul>

        </li>

        <li>

          <a href="/internet/basic-elements/colour">Colour</a>

        </li>

        <li>

          <a href="/internet/basic-elements/typograhpy">Typograhpy</a>

          <ul class="level-2">

            <li>

              <a href="/internet/basic-elements/typograhpy/headings">Headings</a>

            </li>

            <li>

              <a href="/internet/basic-elements/typograhpy/plain-text">Plain Text</a>

            </li>

            <li>

              <a href="/internet/basic-elements/typograhpy/download-fonts">Download Fonts</a>

            </li>

          </ul>

        </li>

        <li>

          <a href="/internet/basic-elements/copy">Copy</a>

          <ul class="level-2">

            <li>

              <a href="/internet/basic-elements/copy/tone-of-voice">Tone of Voice</a>

            </li>

          </ul>

        </li>

        <li>

          <a href="/internet/basic-elements/photography">Photography</a>

        </li>

      </ul>

This is the XSLT:

       <h2>

            <xsl:value-of select="$parentElement/@nodeName"/>

       </h2>





       <ul class="level-1">

            <xsl:for-each select="$parentElement//descendant::node [string(data[@alias='umbracoNaviHide']) != '1'][@level=4][@nodeTypeAlias='Content_Item']">

                  </xsl:call-template>
