Navs

Create grouped navigation controls in various visual layouts.

Page Contents

Overview #

Navigation share general markup and styles, from the base .nav class to the active and disabled states. Swap modifier classes to switch between each style.

Regarding Accessibility #

If you are using navs to provide a navigation bar, be sure to add a role="navigation" to the most logical parent container of the <ul>, or wrap a <nav> element around the whole navigation. Do not add the role to the <ul> itself, as this would prevent it from being announced as an actual list by assistive technologies.

To convey the active state to assistive technologies, use the aria-current attribute — using the page value for current page, or true for the current item in a set.

Note that navigation bars, even if visually styled as tabs with the .nav-tabs class, should not be given role="tablist", role="tab" or role="tabpanel" attributes. These are only appropriate for dynamic tabbed interfaces, as described in the WAI ARIA Authoring Practices. See our Tab widget for an example and additional details.

Disabling Anchors

Please refer to the Accessiblity notes about disabled anchors.

Base Nav #

The base .nav component is built with flexbox and provides a strong foundation for building all types of navigation components. It includes some style overrides (for working with lists), some link padding for larger hit areas, and basic disabled styling. No visual active states are included in the base nav.

<ul class="nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Classes are used throughout, so your markup can be super flexible. Use <ul>s like above, or roll your own with say a <nav> element. Because the .nav uses display: flex, the nav links behave the same as nav items would, but without the extra markup.

<nav class="nav">
<a href="#" class="nav-link active" aria-current="page">Active</a>
<a href="#" class="nav-link">Link</a>
<a href="#" class="nav-link">Link</a>
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Available Styles #

Change the style of .nav components with modifiers and utilities. Mix and match as needed, or build your own.

Horizontal Alignment #

Change the horizontal alignment of your nav with flexbox utilities. By default, navs are left-aligned, but you can easily change them to center or right aligned.

Centered with .flex-center:

<ul class="nav flex-center">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Right-aligned with .flex-end:

<ul class="nav flex-end">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Vertical Alignment #

Stack your navigation by changing the flex item direction with the .flex-column utility. Need to stack them on some viewports but not others? Use the responsive versions (e.g., .flex-sm-column).

<ul class="nav flex-column">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

As always, vertical navigation is possible without <ul>s, too.

<nav class="nav flex-column">
<a href="#" class="nav-link active" aria-current="page">Active</a>
<a href="#" class="nav-link">Link</a>
<a href="#" class="nav-link">Link</a>
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Tabs #

Takes the basic nav from above and adds the .nav-tabs class to generate a tabbed interface. Use them to create tabbable regions with our Tab JavaScript widget.

<ul class="nav nav-tabs">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Pills #

Take that same HTML, but use .nav-pills instead:

<ul class="nav nav-pills">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Vertical Pills #

Add .flex-column to the .nav.nav-pills to stack them vertically. Each .nav-link becomes block-level, allowing for larger hit areas.

<ul class="nav nav-pills flex-column">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

As always, vertical pills are possible without <ul>s.

<nav class="nav nav-pills flex-column">
<a href="#" class="nav-link active" aria-current="page">Active</a>
<a href="#" class="nav-link">Link</a>
<a href="#" class="nav-link">Link</a>
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Fill and Justify #

Force your .nav’s contents to extend the full available width one of two modifier classes. To proportionately fill all available space with your .nav-items, use .nav-fill. Notice that all horizontal space is occupied, but not every nav item has the same width.

<ul class="nav nav-pills nav-fill">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Longer link nav</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

For equal-width elements, use .nav-justify. All horizontal space will be occupied by nav links, but unlike the .nav-fill above, every nav item will be the same width.

<ul class="nav nav-pills nav-justify">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Longer link nav</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Working with Flex Utilities #

If you need responsive nav variations, consider using a series of flexbox utilities. While more verbose, these utilities offer greater customization across responsive breakpoints. In the example below, the nav will be stacked on the lowest breakpoint, then adapt to a horizontal layout that fills the available width starting from the small breakpoint.

<nav class="nav nav-pills flex-column flex-sm-row">
<a href="#" class="flex-sm-fill text-sm-center nav-link active" aria-current="page">Active</a>
<a href="#" class="flex-sm-fill text-sm-center nav-link">Link</a>
<a href="#" class="flex-sm-fill text-sm-center nav-link">Link</a>
<a href="#" class="flex-sm-fill text-sm-center nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Using Dropdowns #

Add dropdown menus with a little extra HTML and the Dropdown JavaScript widget.

Incompatible Widgets

For accessibility reasons, do not mix use of the Tab widget and Dropdown widget in the same nav item. This will cause navigation and usability issues. One or the other, but not both.

Tabs with Dropdowns #

<ul class="nav nav-tabs">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item dropdown">
<a href="#" role="button" class="nav-link" data-cfw="dropdown">Dropdown<span class="caret" aria-hidden="true"></span></a>
<ul class="dropdown-menu">
<li><a href="#" class="dropdown-item">Action</a></li>
<li><a href="#" class="dropdown-item">Another action</a></li>
<li><a href="#" class="dropdown-item">Something else here</a></li>
<li class="dropdown-divider"></li>
<li><a href="#" class="dropdown-item">Separated link</a></li>
</ul>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>

Pills with Dropdowns #

<ul class="nav nav-pills">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Active</a>
</li>
<li class="nav-item dropdown">
<a href="#" role="button" class="nav-link" data-cfw="dropdown">Dropdown<span class="caret" aria-hidden="true"></span></a>
<ul class="dropdown-menu">
<li><a href="#" class="dropdown-item">Action</a></li>
<li><a href="#" class="dropdown-item">Another action</a></li>
<li><a href="#" class="dropdown-item">Something else here</a></li>
<li class="dropdown-divider"></li>
<li><a href="#" class="dropdown-item">Separated link</a></li>
</ul>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
