django-navtag 1.1

A simple Django navigation template tag

A simple Django template tag to handle navigation item selection.

Example

Add the app to your INSTALLED_APPS setting:

INSTALLED_APPS = (
        # ...
        'django_navtag',
)

Give your base template a navigation block something like this:

{% block nav %}
<ul class="nav">
    <li{% if nav.home %} class="selected"{% endif %}>
        <a href="/">Home</a>
    </li>
    <li{% if nav.about %} class="selected"{% endif %}>
        <a href="/about/">About</a>
    </li>
</ul>
{% endblock %}

In your templates, extend the base and set the navigation location:

{% extends "base.html" %}

{% block nav %}
{% nav "home" %}
{{ block.super }}
{% endblock %}

Note

This works for multiple levels of template inheritance, due to the fact that the tag only does anything if the nav context variable does not exist. So only the first {% nav %} call found will ever be processed.

Hierarchical navigation

To create a sub-menu you can check against, simply dot-separate the item:

{% nav "about_menu.info" %}

This will be pass for both {% if nav.about_menu %} and {% if nav.about_menu.info %}.

Using a different context variable

By default, this tag creates a nav context variable. To use an alternate context variable name, call {% nav [item] for [var_name] %}:

{% block nav %}
{% nav "home" for sidenav %}
{{ block.super }}
{% endblock %}
