Navigation - test for child nodes and display not working as expected

Hi There,

I'm having osme issues with my nav macro. I'd like to display all the nodes from the root and test if each node has child nodes and in turn display those.

Your help is much appreciated!

Hi Sean,

Here is how you could get youre navigation to display all nodes and child nodes if any is present and where umbracoNaviHide is not set to true.

<xsl:variable name="parent" select="1111"/> <!-- here you can add your parent NodeID -->
<xsl:variable name="parentNode" select="umbraco.library:GetXmlNodeById($parent)" />
<ul class="sf-menu">
<xsl:for-each select="$parentNode/* [@isDoc][not(umbracoNaviHide = 1)]">
<xsl:element name="li">
<a href="{umbraco.library:NiceUrl(@id)}">
<xsl:value-of select="@nodeName"/>
</a>
<!-- Test if there is any Child Nodes  -->
<xsl:if test="*[@isDoc][not(umbracoNaviHide = 1)]">
<ul>
<xsl:for-each select="./* [@isDoc and string(umbracoNaviHide) !='1']"><xsl:element name="li"><a href="{umbraco.library:NiceUrl(@id)}"><xsl:value-of select="@nodeName"/></a>
</xsl:element>
</xsl:for-each>
</ul>
</xsl:if>
</xsl:element> 
 </xsl:for-each>
</ul>

This is just a way of doing it and from the example am assuming the home or default node will not be displayed.

Hi Fuji,

Thanks very much. I added the code you posted into my macro and it worked like a treat. I used a portion of it for the child nodes recursion.
