    creating an expandable tree using XSLT

    Dear All,

    i want to create an expandable tree that mimics navigation in umbraco backend content. I installed the cog navigation but have no luck to see that the tree is always expanded and shown in menu. Is there anyway for me to display tree based navigation structure by using XSLT.

    Have try using user control approach and Document classes but have no luck to see it works in my case...

     

    any help will be apreciated :)

    Just use XSLT to ouput the full nested list of navigation (perhaps the 'sitemap' XSLT template might be a good place to start) then use javascript to format it into a tree-type menu.  I'ved used this one, which is based on jQuery with success in the past: http://bassistance.de/jquery-plugins/jquery-plugin-treeview/.

    Dear Dan,

    any sample integration between two of them ? (i mean xslt and js)

    Thanks

    Hi

     

    I have this working XSLT for the new schema

    i apply some jquery afterwards.

    this version is expanded from the current page.

    all you need to do is remove th <xsl:if test="count(./*[string(umbracoNaviHide) != '1']) &gt; 0"> part of the xslt.

     

    <?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"

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

    <xsl:param name="currentPage"/>

    <!-- Input the documenttype you want here -->
    <!-- Typically '1' for topnavigtaion and '2' for 2nd level -->
    <!-- Use div elements around this macro combined with css -->
    <!-- for styling the navigation -->
    <xsl:variable name="level" select="1"/>

    <xsl:template match="/">

    Hey guys, have implemented the above menu and its great just what i needed.  Only thing i hoped to solve is:-

    • On my top level nodes i get in brackets the number of links underneath e.g SOME MENU ITEM(12) - how would I remove this number so it no longer appears

     

    • Want to have a hyphen '-' appear before each sub menu to e.g:- Where would I need to place this '-'

     Home

          -Some MENU Item

    Hey Matthew.

    Find this line 

    <xsl:if test="count(./*[@isDoc]) &gt; 0"<span class="subcount"(<xsl:value-ofselect="count(./*[@isDoc])" />)</span></xsl:if>

    delete it or do what i do .

    add
    .subcount {display:none;}
    to your css file. 

    about the hypen

    locate this line and add the hyphen prefixed to this

     <xsl:value-of select="umbraco.library:Item(@id, 'pageName')"/>

    :)

    Thanks for your reply Bo,  I had self worked out how to remove the counter amount of pages ;-)

    With the hyphen, adding it to the line suggested means that all top level nodes also have a hyphen appear.  I hoped to have a hyphen appear only on the sub nodes.  So far instance i have 6 top level nodes, by selecting one of these 6 top level nodes, the menu will then show the sub nodes underneath each with a hyphen.  Any further guidance would be much appreciated.

    The code below is the HTML that was created by a designer:-

    <ul>
        <li><a href="#">SOMEPAGENAME1</a></li>
         <li><a href="#">SOMEPAGENAME2</a></li>
         <li class="current"><a href="#">SOMEPAGENAME3</a>
              <ul>
              <li class="current"><a href="#">- SOMEPAGENAME4</a></li>
              <li ><a href="#">- SOMEPAGENAME5</a></li>
              <li ><a href="#">- SOMEPAGENAME6</a></li>
              </ul>
                                       
      </ul>

    Using the above selecting SOMEPAGENAME4 is the current page being viewed this results in <li class="current"> kikcing in due to it being the current page together with <li class="current"> also in effect on SOMEPAGENAME4 top level node (SOMEPAGENAME3)
