django-treenav

An extensible, hierarchical, and pluggable navigation system for Django sites.

django-treenav was designed from the start to live independent of a CMS implementation. As a separate application, treenav can easily be integrated into existing, custom setups and does not enforce or require users to use a particular content management system.

Sharing the same principals, django-pagelets integrates seamlessly with treenav and can be used together to create a flexible CMS product.

Features

• Generic functionality with multiple URL specifications: get_absolute_url(), reverse(), or raw URLs
• Packaged with templates to render the tree hierarchy with nested <ul>'s, but can easily be overridden with custom templates
• Useful CSS classes for flexible UI customization
• Automatically sets "active" on item and item's parents if PATH_INFO is equal to item.href
• Efficient: minimizes database access with django-mptt functionality
• Caches the tree so that repeated page views to not hit the database.
• Simple links in the MenuItem list view for refreshing the cache and href from the database.

• django
