How to use navigation sidebars


This page is not complete.

Navigation on MDN is frequently done using sidebars that list other articles in a series as well as related content both in the same documentation suite and in other areas of MDN. MDN's sidebars are not created automatically; to include them on the page, you need to create and use a macro of some sort. In this article, we will review the process of both creating MDN sidebar macros and how to use them in an article.

Current MDN sidebar macros

MDN already has a number of macros for creating sidebars. Most are specific to particular sections of MDN, while others are intended to create generic sidebars for documentation areas that don't otherwise have any.

Inserts a sidebar for navigating the add-ons documentation; this is primarily content about creating browser extensions.

Using sidebars

To add a sidebar to a page, find the right macro, then, on the page on to which you want to insert the sidebar, click the "Edit" button. Add to the page a <p> block whose contents are the call to the macro. Once there, you can add the macro call. Typically, sidebar macros don't require any parameters, so you can just do, for example:


Usually, you should do this as the first line of the document. In some documents, it's been done at the bottom instead. This works fine, but for the sake of consistency, try to place it at the top.

If there's already a <p> block with macro calls at the top of the page, such as those that create banners like {{Non-standard_Header}}, you can put the sidebar macro inside the same <p>, like this:
