Primer CSS comes with several navigation components. Some were designed with singular purposes, while others were design to be more flexible and appear quite frequently.
The menu is a vertical list of navigational links. A menu's width and placement must be set by you. If you like, just use our grid columns as a parent. Otherwise, apply a custom
There are a few subcomponents and add-ons that work well with the menu, including avatars, counters, and Octicons.
You can also add optional headings to a menu. Feel free to use nearly any semantic element with the

.UnderlineNav to style navigation with a minimal underlined selected state, typically used for navigation placed at the top of the page. This component comes with variations to accommodate icons, containers and other content.

subnav-search in the subnav bar.
You can also use a
