This plugin enhances navigation usability by combining multiple categories into a single list. This effectively converts a category tree into a list that can be filtered by category, as seen on Cotonti Extensions.
In order for the plugin to work, at least one category code should be configured. Multiple categories can be configured by using comma seperation.
Added support for listfilters.
This extension can also be found on Github. If you want to improve it, extend upon it or add a localisation, please feel free to fork it.
