Rubrics

In a column. The “Rubrics” block is placed in Appearance → Home & blocks, like any other block. By default it shows all sets one after another; if there are many sets and the column grows too long, pick one in Settings → General → “Rubrics in the sidebar”.

In the top bar. When you add an item in Appearance → Menu, there is a list of ready-made rubrics: pick one, and the name and address are filled in for you. This is how a blog rubric gets into the menu in a single step.
