How to create sub-nav when using a structured navigation heirarchy? I have my navigation in a Structure like here and I want to build a sub-navigation on my Information page containing Specials, Reviews, and About, but I can't figure out how.

{% set active_item = craft.entries.section('navigation').nextSiblingOf(48).first() %}


doesn't give me what I need (and I really don't like handling with id's).
There is an nice recipe on the craftcookbook.net site from sprocketeer that explains exactly this.

{% set topEntry = craft.entries.depth(1).slug('information').first() %}
&lt;ul&gt;
    {% nav subEntry in topEntry.getDescendants() %}
        &lt;li&gt;{{ subEntry.title }}
            {% ifchildren %}&lt;ul&gt;{% children %}&lt;/ul&gt;{% endifchildren %}
        &lt;/li&gt;
    {% endnav %}
&lt;/ul&gt;﻿
