Question: I want to use nested categories and set them up. But somehow, they are not rendered in the category area within the navigation bar. What's wrong?

A. To get them all displayed, each category must contain at least one post. So if you have a nested category named Financial|News, both should contain one post. That means: you also need a category named only Financial with one post in addition to Financial|News with one post. It might be preferable to add Financial and Financial|News to your entries so that they show up under the Financial category view as well as the Financial|News category view. However, since many RSS Aggregators only display the first category in their UI, this may not have the desired result (example: RSSBandit would only display Financial, and not Financial and Financial|News.
