How can I only display top level categories in my helpsite (as a basis to browse through the taxonomy structure)?
Our knowledge site users need to be able to browse through the taxonomy to find the articles they are looking for. For this we need to display on the main page only the top level categories. Once one of the top level categories is clicked we need to display the sub categories and the list of articles related to the top category. Then when a sub category is clicked we need to display any sub-sub categories and articles that are related to the subcategory.
What is the recommended way to implement this?
Currently the categories are all displayed (no matter their relative level in the taxonomy structure) on the starting screen. What is the rationale for this?
