=== Limiting the TOC's content depth ===
{{Shortcut|H:LIMITTOC}}
By default, the TOC includes all the headings in the page, whatever their level. When an article or project page has a very large number of subsections, it may be appropriate to hide lower-level subsections from the TOC. You can specify a limit for the lowest-level section that should be displayed using {{tlx|TOC limit|<var>n</var>}}, where <code><var>n</var></code> is the number of <code>=</code> signs that are used on each side of the lowest-level section header that should be displayed (e.g. <code>3</code> to show all headings down to <code><nowiki>===sub-sections===</nowiki></code> but hide <code><nowiki>====sub-sub-sections====</nowiki></code> and all headings below that). The <code>limit=<var>n</var></code> parameter can also be given to {{tlnull|TOC left}} or {{tlnull|TOC right}} the same way.
