I have a hierarchical taxonomy, and I'm currently using the Taxonomy Menu module to display navigation links. E.g.
+ Dairy * Milk * Cream + Fruit n Veges + Citrus * Lemon * Lime * Pumpkin * Tomato
Each of the links refers to a taxonomy page, which is nice, but the page for "Dairy" only includes nodes that have the term "Dairy". It doesn't include "Milk" and "Cream" nodes, for example, which is what I want.
What's the best way to implement this? And "what's the point" of sub-terms, if they don't seem to have any semantic meaning?
