Dan,

1. Add an extra parameter in your template call and check the value of that variable

<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:call-template name="drawNodes">
<xsl:with-param name="parent" select="."/>
<xsl:with-param name="topLevel" select="0"/>
</xsl:call-template>...

<xsl:template name="drawNodes">
<xsl:param name="parent"/>
<xsl:param name="topLevel"/>...

<ul>
<xsl:if test="string($topLevel) = '1'">
<xsl:attribute name="class"><xsl:text>myClass</xsl:text></xsl:attribute>
<xsl:attribute name="id"><xsl:text>myId</xsl:text></xsl:attribute>
</xsl:if>...

2. Add a check on the list element

<li>
<xsl:if test="./ancestor-or-self::node [@id = ./@id">
<xsl:attribute name="class"><xsl:text>selected</xsl:text></xsl:attribute>
</xsl:if>
<a href="{umbraco.library:NiceUrl(@id)}"><xsl:value-of select="@nodeName"/></a>

May need some tweaks (as i'm writing this down from top of my head..)

Hope this helps.

You could also take a look at this navigation package, it contains working examples of all you want to achieve and more. So it might save you a bit of time writing all that pesky xslt! ;-)

Thanks Tim - I tried that package but by default it didn't write out all of my navigation (I'm using 'Suckerfish' and jQuery to hide the unselected elements, so need the full navigation to be written out to HTML) so immediately I was a bit stumped.

Thanks too Dirk.  I've implemented point 1 but when I save it errors:

Error occured

Any ideas?  I suspect it's because of the "." in the line: <xsl:with-param name="parent" select="."/>, but really I have no idea!

Thanks

Hmm, the second part error also.  I think this is because of a typo.  I changed it to:

<xsl:if test="./ancestor-or-self::node [@id = ./@id]">
<xsl:attribute name="class"><xsl:text>current</xsl:text></xsl:attribute>
</xsl:if>

Note: added the closing square bracket in the first line.

However, this has just added the class to all '<li>' tags.

Hi Dan,

No worries, keep your eyes peeled for the next version of the package (as it will be able to write the whole nav out at once, with selected and branch classes all working). I'm hoping to release it later today!
