Hi,

Forgive all my XSLT questions today, I'm working on some navigation...

I have a two-level nested list navigation system, which works great using the code below:

<?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" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
    exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">

    <xsl:output method="xml" omit-xml-declaration="yes"/>
    <xsl:param name="currentPage"/>
    <xsl:variable name="maxLevelForNav" select="3"/>

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

    <xsl:template name="drawNodes">
        <xsl:param name="parent"/> 
        <xsl:param name="topLevel"/>
        <xsl:if test="umbraco.library:IsProtected($parent/@id, $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, $parent/@path) = 1 and umbraco.library:IsLoggedOn() = 1)">
            <ul>
                <xsl:if test="string($topLevel) = '1'">
                    <xsl:attribute name="id"><xsl:text>nav</xsl:text></xsl:attribute>
                    <xsl:attribute name="class"><xsl:text>sf-menu sf-navbar</xsl:text></xsl:attribute>
                </xsl:if>
                <xsl:for-each select="$parent/node [string(./data [@alias='umbracoNaviHide']) != '1' and @level &lt;= $maxLevelForNav]"> 
                    <li>
                        <xsl:if test="$currentPage/@id = current()/@id">
                            <xsl:attribute name="class"><xsl:text>current</xsl:text></xsl:attribute>
                        </xsl:if>
                        <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;= $maxLevelForNav]) &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>

At the moment it correctly applies a class of 'active' to a selected list item, but it doesn't apply that class to the first level list when you get into the second level.  What I want to do is to keep the class of 'active' in the li tag of the top level of nav when it's sub-nav is selected.

Does anyone know how to achieve this?

Thanks folks...
