Explorer Theme for Trac

This theme displays your Trac wiki in an explorer like style. The browse-able structure of pages is based on tags and the sub-page hierarchy. Trac is an open source, Web-based project management and issue tracking system.

It's as easy as that

Browse the wiki to find the pages by tags and parent pages. Expand and collapse the tags and pages by clicking on the plus and minus signs.

It's free
