Accessing content for one of the 4 main categories in `/learn`

[hfrick]

On https://www.tidymodels.org/learn/, what's the best way to get all articles under e.g. statistics, or models?

Clicking on the left-hand menu gives a drop-down menu but

• I think it'd be nicer to get the same result as when clicking on one of the categories in the right-hand menu
• the drop-down menu does not always contain all articles under that folder, e.g for models/

Is there something we could do to the left-hand menu? Or should we reduce the number of categories in the right-hand menu?
