Suggestion for database driven navigation

[eluser]FuzzyJared[/eluser]
The links would generate from the database yes.
Basically I have Content Groups, Content Categories and then Content Pages.
The content groups are used to spit out the appropriate groups in the right area of the template, and then the categories are used to split up the grouping of content with <ul>'. And then the links are in <li> elements.

Producing the links are not hard, I was just looking for a better alternative to something like $data['info_nav'] = $this->get_info_nav(); and then feeding the data to the $data to the leftcol.php page that I have.
