Template: TOC limit
This template inserts a Table of Contents which omits subheadings beyond a certain depth. The table obeys the same layout rules as the __TOC__ magic word. Omitted sections still have section edit links in the article body; the main use for this template is situations where you want section edit links for ease of editing but don't want to clutter the table of contents.
Place the below code at the top of the page, replace # with heading level you want.
Alternatively you can use:
which would assume the default level 3.
