Hello,

Beginner Umbraco user here, but am a Sitecore-certified developer, and notice an amazing number of similarities between the platforms. Must be a coincidence.

Anyway, I'm building a top nav menu where I just want to render the whole tree of Content items under 'Home' as nested unordered lists. Umbraco xsl seems to work a little differently that what I'm used to, so I want to ask if there's a better way to do it than this:

Code:

<xsl:param name="parent">Home</xsl:param>

<xsl:template match="/">
    <xsl:call-template name="menu">
    <xsl:with-param name="parent" select="$parent"/>
    </xsl:call-template>
</xsl:template>

<xsl:template name="menu">

    <xsl:param name="parent"/>
    <ul>

    <!-- add css class for topmost ul -->
    <xsl:if test="$parent='Home'">
        <xsl:attribute name="class">top_menu</xsl:attribute>
    </xsl:if>

    <!-- iterate over all elements of the current level -->
    <xsl:for-each select="$currentPage/ancestor::root//node[@nodeName=$parent]/node [string(data [@alias='umbracoNaviHide']) != '1']">
        <li>
          <a href="{umbraco.library:NiceUrl(@id)}">
            <xsl:if test="$currentPage/ancestor-or-self::node/@id = current()/@id">
              <xsl:attribute name="class">nav_selected</xsl:attribute>
            </xsl:if>
            <xsl:value-of select="@nodeName"/>
          </a>

         
          <!-- test for children, recurse if found -->   
          <xsl:if test="count(descendant::node [string(data [@alias='umbracoNaviHide']) != '1']) > 0">
            <xsl:call-template name="menu"><xsl:with-param name="parent" select="@nodeName"/></xsl:call-template>
          </xsl:if>

        </li>
      </xsl:for-each>
    </ul>

</xsl:template>


Thanks,
- Andrew

Hi there

try looking at the "sitemap" xslt.


Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:Stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxml="urn:schemas-microsoft-com:xslt" xmlns:umbraco.library="urn:umbraco.library" exclude-result-prefixes="msxml
umbraco.library">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<!-- update this variable on how deep your site map should be -->
<xsl:variable name="maxLevelForSitemap" select="5"/>

<xsl:template match="/">
    <div id="main_nav">
        <xsl:call-template name="drawNodes"> 
            <xsl:with-param name="parent" select="$currentPage/ancestor-or-self::node [@level=1]"/> 
        </xsl:call-template>
    </div>
</xsl:template>

<xsl:template name="drawNodes">
    <xsl:param name="parent"/>
    <xsl:if test="umbraco.library:IsProtected($parent/@id, $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, $parent/@path) = 1 and umbraco.library:IsLoggedOn() = 1)">
        <ul>
            <xsl:for-each select="$parent/node [string(./data [@alias='umbracoNaviHide']) != '1' and @level &lt;= $maxLevelForSitemap]">
                <xsl:if test="(string(@level) = '2') and (position() = 1)">
                    <li style="margin-left:8px;"><a class="homelink" href="{umbraco.library:NiceUrl(1070)}" >Home</a></li>
                </xsl:if>       
                <li> 
                    <a href="{umbraco.library:NiceUrl(@id)}">
                    <xsl:value-of select="@nodeName"/></a> 
                    <xsl:if test="count(./node [string(./data [@alias='umbracoNaviHide']) != '1' and @level &lt;= $maxLevelForSitemap]) &gt; 0">   
                        <xsl:call-template name="drawNodes">   
                        <xsl:with-param name="parent" select="."/>   
                        </xsl:call-template> 
                    </xsl:if>
                </li>
            </xsl:for-each>
        </ul>
    </xsl:if>
</xsl:template>
</xsl:stylesheet>


That should do it, or at least be a good starting point.
