Documentation

Primer 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 width.

```html title=”Menu”


There are a few subcomponents and add-ons that work well with the menu, including avatars, counters, and Octicons.

```erb title="Menu with octicons, avatars and counters"
<nav class="menu" aria-label="Person settings">
  <a class="menu-item selected" href="#url" aria-current="page">
    <%= octicon "tools" %>
    Account
  </a>
  <a class="menu-item" href="#url">
    <%= octicon "person" %>
    Profile
  </a>
  <a class="menu-item" href="#url">
    <%= octicon "mail" %>
    Emails
  </a>
  <a class="menu-item" href="#url">
    <%= octicon "radio-tower" %>
    <span class="Counter">3</span>
    Notifications
  </a>
</nav>

You can also add optional headings to a menu. Feel free to use nearly any semantic element with the .menu-heading class, including inline elements, headings, and more.

```html title=”Menu with heading”


## Underline nav

Use `.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.

```html title="UnderlineNav"
<nav class="UnderlineNav">
  <div class="UnderlineNav-body">
    <a href="#url" role="tab" title="Item 1" class="UnderlineNav-item selected">Item 1</a>
    <a href="#url" role="tab" title="Item 2" class="UnderlineNav-item">Item 2</a>
    <a href="#url" role="tab" title="Item 3" class="UnderlineNav-item">Item 3</a>
    <a href="#url" role="tab" title="Item 4" class="UnderlineNav-item">Item 4</a>
  </div>
</nav>

Use .UnderlineNav-actions to place another element, such as a button, to the opposite side of the navigation items.

```html title=”UnderlineNav-actions”


Use `.UnderlineNav--right` to right align the navigation.

```html title="UnderlineNav--right"
<nav class="UnderlineNav UnderlineNav--right">
  <div class="UnderlineNav-body">
    <a href="#url" role="tab" title="Item 1" class="UnderlineNav-item selected">Item 1</a>
    <a href="#url" role="tab" title="Item 2" class="UnderlineNav-item">Item 2</a>
    <a href="#url" role="tab" title="Item 3" class="UnderlineNav-item">Item 3</a>
    <a href="#url" role="tab" title="Item 4" class="UnderlineNav-item">Item 4</a>
  </div>
</nav>

.UnderlineNav--right also works with when used with .UnderlineNav-actions.

```html title=”UnderlineNav–right with actions”


<!-- Update wording here -->
`.Counters` and `.octicons` can be used with navigation items. Use `.UnderlineNav-octicon` to add color and hover styles.

```erb title="UnderlineNav with Counter"
<nav class="UnderlineNav" aria-label="Foo bar">
  <div class="UnderlineNav-body">
    <a href="#url" class="UnderlineNav-item selected">
      <%= octicon "tools", :class => "UnderlineNav-octicon" %>
      Item 1
    </a>
    <a href="#url" class="UnderlineNav-item">
      <%= octicon "tools", :class => "UnderlineNav-octicon" %>
      Item 2
      <span class="Counter">10</span>
     </a>
     <a href="#url" class="UnderlineNav-item">
       <%= octicon "tools", :class => "UnderlineNav-octicon" %>
       Item 3
    </a>
    <a href="#url" class="UnderlineNav-item">
      <%= octicon "tools", :class => "UnderlineNav-octicon" %>
      Item 4
     </a>
  </div>
</nav>

Use .UnderlineNav--full in combination with container styles and .UnderlineNav-container to make navigation fill the width of the container.

```html title=”UnderlineNav–full”


## Tabnav

When you need to toggle between different views, consider using a tabnav. It'll given you a left-aligned horizontal row of... tabs!

```html title="tabnav"
<div class="tabnav">
  <nav class="tabnav-tabs" aria-label="Foo bar">
    <a href="#url" class="tabnav-tab selected" aria-current="page">Foo tab</a>
    <a href="#url" class="tabnav-tab">Bar tab</a>
  </nav>
</div>

Use .float-right to align additional elements in the .tabnav:

```html title=”tabnav with buttons”

Button

Additional bits of text and links can be styled for optimal placement with `.tabnav-extra`:

```html title="tabnav-extra"
<div class="tabnav">
  <div class="tabnav-extra float-right">
    Tabnav widget text here.
  </div>
  <nav class="tabnav-tabs" aria-label="Foo bar">
    <a href="#url" class="tabnav-tab selected" aria-current="page">Foo Tab</a>
    <a href="#url" class="tabnav-tab">Bar Tab</a>
  </nav>
</div>

```html title=”tabnav with everything”


## Filter list

A vertical list of filters. Grey text on white background. Selecting a filter from the list will fill its background with blue and make the text white.

```html title="filter-list"
<ul class="filter-list">
  <li>
    <a href="#url" class="filter-item selected" aria-current="page">
      <span class="count" title="results">21</span>
      First filter
    </a>
  </li>
  <li>
    <a href="#url" class="filter-item">
      <span class="count" title="results">3</span>
      Second filter
    </a>
  </li>
  <li>
    <a href="#url" class="filter-item">
      Third filter
    </a>
  </li>
</ul>

.subnav is navigation that is typically used when on a dashboard type interface with another set of navigation above it. This helps distinguish navigation hierarchy.

```html title=”subnav”


You can have `subnav-search` in the subnav bar.

```erb title="subnav-search"
<div class="subnav">
  <nav class="subnav-links" aria-label="Repository">
    <a href="#url" class="subnav-item selected" aria-current="page">Item 1</a>
    <a href="#url" class="subnav-item">Item 2</a>
    <a href="#url" class="subnav-item">Item 3</a>
  </nav>
  <div class="subnav-search float-left">
    <input type="search" name="name" class="form-control subnav-search-input" value="" aria-label="Search site">
    <%= octicon "search", :class => "subnav-search-icon" %>
  </div>
</div>

You can also use a subnav-search-context to display search help in a select menu.

```erb title=”subnav-search-context”

```
