Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.

Wrap the dropdown's trigger and the dropdown menu within .dropdown, or another element that declares position: relative;. Then add the menu's HTML.

{% highlight html %} {% endhighlight %}

Add .pull-right to a .dropdown-menu to right align the dropdown menu.

{% highlight html %} {% endhighlight %}

Add a header to label sections of actions in any dropdown menu.

{% highlight html %} {% endhighlight %}

Add .disabled to a <li> in the dropdown to disable the link.

{% highlight html %} {% endhighlight %}

Group a series of buttons together on a single line with the button group. Add on optional JavaScript radio and checkbox style behavior with our buttons plugin.

Tooltips & popovers in button groups require special setting

When using tooltips or popovers on elements within a .btn-group, you'll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).

Basic example

Wrap a series of buttons with .btn in .btn-group.

{% highlight html %}
{% endhighlight %}

Button toolbar

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

{% highlight html %}
...
...
...
{% endhighlight %}

Sizing

Instead of applying button sizing classes to every button in a group, just add .btn-group-* to the .btn-group.

{% highlight html %}
...
...
...
...
{% endhighlight %}

Nesting

Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.

{% highlight html %}
{% endhighlight %}

Vertical variation

Make a set of buttons appear vertically stacked rather than horizontally.

{% highlight html %}
...
{% endhighlight %}

Justified link variation

Make a group of buttons stretch at the same size to span the entire width of its parent.

Element-specific usage

This only works with <a> elements as the <button> doesn't pick up these styles.

{% highlight html %}
...
{% endhighlight %}

Use any button to trigger a dropdown menu by placing it within a .btn-group and providing the proper menu markup.

Plugin dependency

Button dropdowns require the dropdown plugin to be included in your version of Bootstrap.

Single button dropdowns

Turn a button into a dropdown toggle with some basic markup changes.

{% highlight html %}
{% endhighlight %}

Split button dropdowns

Similarly, create split button dropdowns with the same markup changes, only with a separate button.

{% highlight html %}
{% endhighlight %}

Sizing

Button dropdowns work with buttons of all sizes.

{% highlight html %}
{% endhighlight %}

Dropup variation

Trigger dropdown menus above elements by adding .dropup to the parent.

{% highlight html %}
{% endhighlight %}

Extend form controls by adding text or buttons before, after, or on both sides of any text-based input. Use .input-group with an .input-group-addon to prepend or append elements to a .form-control.

Cross-browser compatibility

Avoid using <select> elements here as they cannot be fully styled in WebKit browsers.

Tooltips & popovers in input groups require special setting

When using tooltips or popovers on elements within an .input-group, you'll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).

Basic example

@

.00

$ .00
{% highlight html %}
@
.00
$ .00
{% endhighlight %}

Sizing

Add the relative form sizing classes to the .input-group itself and contents within will automatically resizeā€”no need for repeating the form control size classes on each element.

Checkboxes and radio addons

Place any checkbox or radio option within an input group's addon instead of text.

{% highlight html %}
{% endhighlight %}

Button addons

Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon, you'll need to use .input-group-btn to wrap the buttons. This is required due to default browser styles that cannot be overridden.

Segmented buttons

Navs available in Bootstrap have shared markup, starting with the base .nav class, as well as shared states. Swap modifier classes to switch between each style.

Note the .nav-tabs class requires the .nav base class.

{% highlight html %} {% endhighlight %}

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

{% highlight html %} {% endhighlight %}

Pills are also vertically stackable. Just add .nav-stacked.

{% highlight html %} {% endhighlight %}

Easily make tabs or pills equal widths of their parent with .nav-justified.


{% highlight html %} {% endhighlight %}

For any nav component (tabs, pills, or list), add .disabled for gray links and no hover effects.

Link functionality not impacted

This class will only change the <a>'s appearance, not its functionality. Use custom JavaScript to disable links here.

{% highlight html %} {% endhighlight %}

To align nav links, use the .pull-left or .pull-right utility classes. Both classes will add a CSS float in the specified direction.

Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.

Tabs with dropdowns

Navbars are responsive meta components that serve as navigation headers for your application or site. They begin collapsed (and are toggleable) in mobile views and become horizontal as the available viewport width increases.

Customize the collapsing point

Depending on the content in your navbar, you might need to change the point at which your navbar switches between collapsed and horizontal mode. Customize the @grid-float-breakpoint variable or add your own media query.

{% highlight html %} {% endhighlight %}

Plugin dependency

The responsive navbar requires the collapse plugin to be included in your version of Bootstrap.

Make navbars accessible

Be sure to add a role="navigation" to every navbar to help with accessibility.

For buttons not residing in a <form>, add this class to vertically center buttons within a navbar.

{% highlight html %} {% endhighlight %}

Wrap strings of text in an element with .navbar-text, usually on a <p> tag for proper leading and color.

{% highlight html %} {% endhighlight %}

For folks using standard links that are not within the regular navbar navigation component, use the .navbar-link class to add the proper colors for the default and inverse navbar options.

{% highlight html %} {% endhighlight %}

Align nav links, forms, buttons, or text, using the .navbar-left or .navbar-right utility classes. Both classes will add a CSS float in the specified direction. For example, to align nav links, put them in a separate <ul> with the respective utility class applied.

These classes are mixin-ed versions of .pull-left and .pull-right, but they're scoped to media queries for easier handling of navbar components across device sizes.

Add .navbar-fixed-top.

{% highlight html %} {% endhighlight %}

Body padding required

The fixed navbar will overlay your other content, unless you add padding to the top of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.

{% highlight css %} body { padding-top: 70px; } {% endhighlight %}

Make sure to include this after the core Bootstrap CSS.

Add .navbar-fixed-bottom instead.

{% highlight html %} {% endhighlight %}

Body padding required

The fixed navbar will overlay your other content, unless you add padding to the bottom of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.

{% highlight css %} body { padding-bottom: 70px; } {% endhighlight %}

Make sure to include this after the core Bootstrap CSS.

Create a full-width navbar that scrolls away with the page by adding .navbar-static-top. Unlike the .navbar-fixed-* classes, you do not need to change any padding on the body.

{% highlight html %} {% endhighlight %}

Modify the look of the navbar by adding .navbar-inverse.

{% highlight html %} {% endhighlight %}

Indicate the current page's location within a navigational hierarchy.

Separators are automatically added in CSS through :before and content.

{% highlight html %} {% endhighlight %}

Provide pagination links for your site or app with the multi-page pagination component, or the simpler pager alternative.

Default pagination

Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.

{% highlight html %} {% endhighlight %}

Disabled and active states

Links are customizable for different circumstances. Use .disabled for unclickable links and .active to indicate the current page.

{% highlight html %} {% endhighlight %}

You can optionally swap out active or disabled anchors for <span> to remove click functionality while retaining intended styles.

{% highlight html %} {% endhighlight %}

Sizing

Fancy larger or smaller pagination? Add .pagination-lg or .pagination-sm for additional sizes.

{% highlight html %} {% endhighlight %}

Pager

Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.

Default example

By default, the pager centers links.

{% highlight html %} {% endhighlight %}

Aligned links

Alternatively, you can align each link to the sides:

{% highlight html %} {% endhighlight %}

Optional disabled state

Pager links also use the general .disabled utility class from the pagination.

{% highlight html %} {% endhighlight %}

Available variations

Add any of the below mentioned modifier classes to change the appearance of a label.

Default Primary Success Info Warning Danger
{% highlight html %} Default Primary Success Info Warning Danger {% endhighlight %}

Easily highlight new or unread items by adding a <span class="badge"> to links, Bootstrap navs, and more.

Inbox 42
{% highlight html %} Inbox 42 {% endhighlight %}

Self collapsing

When there are no new or unread items, badges will simply collapse (via CSS's :empty selector) provided no content exists within.

Cross-browser compatibility

Badges won't self collapse in Internet Explorer 8 because it lacks support for the :empty selector.

Adapts to active nav states

Built-in styles are included for placing badges in active states in pill and list navigations.

Provide up-to-date feedback on the progress of a workflow or action with simple yet flexible progress bars.

Cross-browser compatibility

Progress bars use CSS3 transitions and animations to achieve some of their effects. These features are not supported in Internet Explorer 9 and below or older versions of Firefox. Opera 12 does not support animations.

Basic example

Default progress bar with a vertical gradient.

{% highlight html %} {% endhighlight %}

List groups are a flexible and powerful component for displaying not only simple lists of elements, but complex ones with custom content.

Basic example

The most basic list group is simply an unordered list with list items, and the proper classes. Build upon it with the options that follow, or your own CSS as needed.

{% highlight html %} {% endhighlight %}

Badges

Add the badges component to any list group item and it will automatically be positioned on the right.

{% highlight html %} {% endhighlight %}

Linked items

Linkify list group items by using anchor tags instead of list items (that also means a parent <div> instead of an <ul>). No need for individual parents around each element.

{% highlight html %}
Cras justo odio Dapibus ac facilisis in Morbi leo risus Porta ac consectetur ac Vestibulum at eros
{% endhighlight %}

Custom content

Add nearly any HTML within, even for linked list groups like the one below.

{% highlight html %}
