I've created a menu in umbraco using XSLT. The menu is using the usual ul and li elements and I'm displaying only the first level of the menu. The aim is to create a menu that expands to show the sub menu when I click a parent
node (in the top level).
I am after the xslt I would need to expose the sub menu when clicked.
I think I would need to make use of ancestor-or-self to detect the current menu and parent menu and display them and also the $currentPage variable.
I have the following xslt:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp " "> ]>
<xsl:stylesheet
version="1.0"

<xsl:variable name="level" select="@level" />

<xsl:for-each select="$parent/node [string(./data [@alias='showInMenu']) = 1]">
<li>
<a href="/kb{umbraco.library:NiceUrl(@id)}">
<xsl:value-of select="@nodeName"/>

<xsl:variable name="level" select="@level" />
<xsl:if test="(count(./node [string(./data [@alias='showInMenu']) = '1']) > 0)">
<xsl:call-template name="drawNodes">

</xsl:template>
</xsl:stylesheet>
I suspect this could be improved using apply-templates, but I'm not yet up to speed with that (this being only the second day of my learning xslt).
My menu:
Item 1
Item 2
Item 3
Item 4
when I click on Item 2 I want to see it's child menu too:
Item 1
Item 2
-- Item 2.1
-- Item 2.2
Item 3
Item 4
and so on down the nested menu.
