Navigation Tags

Provides hierarchical tree navigation based on Radiant's site structure. Outputs navigation in the form of a -very flexible and CSS'able- unordered list. Also provides r:if_self and r:if_ancestor_or_self

Usage

<r:nav [root=“/”] [include_root=“true”] [depth=“2”] [expand_all=“true”] [ids_for_lis=“true”] />

Given this directory tree:

  • Home

    • About

      • Contact us

    • Blog

      • First Article

      • Second Article

    • Catalog

<r:nav depth=“2” /> would output a navigation list like:

<ul>

<li class="parent_of_current has_children"><a href="/about/">About</a>
  <ul>
    <li class="current"><a href="/about/contact">Contact Us</a></li>
  </ul>
</li>
<li class="has_children"><a href="/blog/">Blog</a></li>
<li class="has_children"><a href="/catalogue">Catalogue</a></li>

</ul>

Use only and except to filter which pages are included. The following would output a navigation list only containing only the pages articles, or notices, or their descendants, and which aren't css, javascript, or xml pages:

<r:nav only=“^/(articles|notices)/” except=“.(css|js|xml)/*$” />

Available tag attributes:

  • root defaults: to “/”, where to start building the navigation from, you can i.e. use “/products” to build a subnav

  • include_root: defaults to false, set to true to include the root page (i.e. Home)

  • ids_for_lis: defaults to false, enable this to give each li an id (it's slug prefixed with nav_)

  • ids_for_links: defaults to false, enable this to give each link an id (it's slug prefixed with nav_)

  • depth: defaults to 1, which means no sub-ul's, set to 2 or more for a nested list

  • expand_all: defaults to false, enable this to have all li's create sub-ul's of their children, i.o. only the currently active li

  • only: a string or regular expresssion. only pages whose urls match this are included

  • except: a string or regular expresssion. pages whose urls match this are not shown. except will override only. use to eliminate non-content file-types

  • id, class, monkeyballs, … will be used as html attributes for the ul
