Articles Count for K2
The articles count module (as the name suggests), counts the number of articles in your K2 categories, and displays the numbers in a list with a link to the category. There are a variety of options available, including which categories to display, and whether to display empty categories.
The categories can be displayed either as a simple list or a collapsible tree. The tree shows the category structure, with parent-child relationships.
