Overview

Individual or compiled

Plugins can be included individually (using Bootstrap's individual *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js).

Do not attempt to include both.

Both bootstrap.js and bootstrap.min.js contain all plugins in a single file.

Plugin dependencies

Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files).

Data attributes

You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first-class API and should be your first consideration when using a plugin.

That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the document namespaced with data-api. This looks like this: {% highlight js %} $(document).off('.data-api') {% endhighlight %}

Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:

{% highlight js %} $(document).off('.alert.data-api') {% endhighlight %}

Programmatic API

We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.

{% highlight js %} $(".btn.danger").button("toggle").addClass("fat") {% endhighlight %}

All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):

{% highlight js %} $("#myModal").modal() // initialized with defaults $("#myModal").modal({ keyboard: false }) // initialized with no keyboard $("#myModal").modal('show') // initializes and invokes show immediately

{% endhighlight %}

Each plugin also exposes its raw constructor on a Constructor property: $.fn.popover.Constructor. If you'd like to get a particular plugin instance, retrieve it directly from an element: $('[rel=popover]').data('popover').

No conflict

Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call .noConflict on the plugin you wish to revert the value of.

{% highlight js %} var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value $.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality {% endhighlight %}

Events

Bootstrap provides custom events for most plugin's unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. show) is triggered at the start of an event, and its past participle form (ex. shown) is trigger on the completion of an action.

As of 3.0.0, all Bootstrap events are namespaced.

All infinitive events provide preventDefault functionality. This provides the ability to stop the execution of an action before it starts.

{% highlight js %} $('#myModal').on('show.bs.modal', function (e) { if (!data) return e.preventDefault() // stops modal from being shown }) {% endhighlight %}

Third-party libraries

Bootstrap does not officially support third-party JavaScript libraries like Prototype or jQuery UI. Despite .noConflict and namespaced events, there may be compatibility problems that you need to fix on your own. Ask on the mailing list if you need help.

Transitions transition.js

About transitions

For simple transition effects, include transition.js once alongside the other JS files. If you're using the compiled (or minified) bootstrap.js, there is no need to include this—it's already there.

What's inside

Transition.js is a basic helper for transitionEnd events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.

Modals modal.js

Examples

Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.

Static example

A rendered modal with header, body, and set of actions in the footer.

Modal title

One fine body…

{% highlight html %}

Modal title

One fine body…

{% endhighlight %}

Live demo

Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.

Launch demo modal
{% highlight html %} Launch demo modal {% endhighlight %}

Make modals accessible

Be sure to add role="dialog" to your primary modal div. In the example above, div#myModal.
Also, the aria-labelledby attribute references your modal title. In this example, h4#myModalLabel.
Finally, aria-hidden="true" tells assistive technologies to skip DOM elements.
Additionally, you may give a description of your modal dialog. Use the aria-describedby attribute in the modal's primary <div> to point to this description (this is not shown in the above example).

Usage

Via data attributes

Activate a modal without writing JavaScript. Set data-toggle="modal" on a controller element, like a button, along with a data-target="#foo" or href="#foo" to target a specific modal to toggle.

{% highlight html %} {% endhighlight %}

Via JavaScript

Call a modal with id myModal with a single line of JavaScript:

{% highlight js %}$('#myModal').modal(options){% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-backdrop="".

Name type default description
backdrop boolean true Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click.
keyboard boolean true Closes the modal when escape key is pressed
show boolean true Shows the modal when initialized.
remote path false

If a remote URL is provided, content will be loaded via jQuery's load method and injected into the root of the modal element. If you're using the data api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

{% highlight html %} Click me {% endhighlight %}

Methods

.modal(options)

Activates your content as a modal. Accepts an optional options object.

{% highlight js %} $('#myModal').modal({ keyboard: false }) {% endhighlight %}

.modal('toggle')

Manually toggles a modal.

{% highlight js %}$('#myModal').modal('toggle'){% endhighlight %}

.modal('show')

Manually opens a modal.

{% highlight js %}$('#myModal').modal('show'){% endhighlight %}

.modal('hide')

Manually hides a modal.

{% highlight js %}$('#myModal').modal('hide'){% endhighlight %}

Events

Bootstrap's modal class exposes a few events for hooking into modal functionality.

Event Type Description
show.bs.modal This event fires immediately when the show instance method is called.
shown.bs.modal This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.modal This event is fired immediately when the hide instance method has been called.
hidden.bs.modal This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
{% highlight js %} $('#myModal').on('hidden.bs.modal', function () { // do something… }) {% endhighlight %}

Dropdowns dropdown.js

Add dropdown menus to nearly anything with this simple plugin, including the navbar, tabs, and pills.

Within a navbar

Within tabs

Via data attributes

Add data-toggle="dropdown" to a link or button to toggle a dropdown.

{% highlight html %}
Dropdown trigger
{% endhighlight %}

To keep URLs intact, use the data-target attribute instead of href="#".

{% highlight html %}
Dropdown
{% endhighlight %}

Via JavaScript

Call the dropdowns via JavaScript:

{% highlight js %} $('.dropdown-toggle').dropdown() {% endhighlight %}

Options

None

Methods

$().dropdown('toggle')

Toggles the dropdown menu of a given navbar or tabbed navigation.

Events

Event Type Description
show.bs.dropdown This event fires immediately when the show instance method is called.
shown.bs.dropdown This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete).
hide.bs.dropdown This event is fired immediately when the hide instance method has been called.
hidden.bs.dropdown This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete).
{% highlight js %} $('#myDropdown').on('show.bs.dropdown', function () { // do something… }) {% endhighlight %}

ScrollSpy scrollspy.js

Example in navbar

The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the area below the navbar and watch the active class change. The dropdown sub items will be highlighted as well.

Usage

Via data attributes

To easily add scrollspy behavior to your topbar navigation, add data-spy="scroll" to the element you want to spy on (most typically this would be the <body>. Then add the data-target attribute with the ID or class of the parent element of any Bootstrap .nav component.

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

Via JavaScript

Call the scrollspy via JavaScript:

{% highlight js %} $('body').scrollspy({ target: '#navbar-example' }) {% endhighlight %}

Resolvable ID targets required

Navbar links must have resolvable id targets. For example, a <a href="#home">home</a> must correspond to something in the DOM like <div id="home"></div>.

Methods

.scrollspy('refresh')

When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:

{% highlight js %} $('[data-spy="scroll"]').each(function () { var $spy = $(this).scrollspy('refresh') }) {% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset="".

Name type default description
offset number 10 Pixels to offset from top when calculating position of scroll.

Events

Event Type Description
activate.bs.scrollspy This event fires whenever a new item becomes activated by the scrollspy.
{% highlight js %} $('#myScrollspy').on('activate.bs.scrollspy', function () { // do something… }) {% endhighlight %}

Togglable tabs tab.js

Example tabs

Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus.

Usage

Enable tabbable tabs via JavaScript (each tab needs to be activated individually):

{% highlight js %} $('#myTab a').click(function (e) { e.preventDefault() $(this).tab('show') }) {% endhighlight %}

You can activate individual tabs in several ways:

{% highlight js %} $('#myTab a[href="#profile"]').tab('show') // Select tab by name $('#myTab a:first').tab('show') // Select first tab $('#myTab a:last').tab('show') // Select last tab $('#myTab li:eq(2) a').tab('show') // Select third tab (0-indexed) {% endhighlight %}

Markup

You can activate a tab or pill navigation without writing any JavaScript by simply specifying data-toggle="tab" or data-toggle="pill" on an element. Adding the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling.

{% highlight html %} {% endhighlight %}

To make tabs fade in, add .fade to each .tab-pane.

Methods

$().tab

Activates a tab element and content container. Tab should have either a data-target or an href targeting a container node in the DOM.

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

Events

Event Type Description
show.bs.tab This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
shown.bs.tab This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
{% highlight js %} $('a[data-toggle="tab"]').on('shown.bs.tab', function (e) { e.target // activated tab e.relatedTarget // previous tab }) {% endhighlight %}

Tooltips tooltip.js

Examples

Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.

Hover over the links below to see tooltips:

Four directions

Tooltips in button groups and input groups require special setting

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

Usage

Trigger the tooltip via JavaScript:

{% highlight js %} $('#example').tooltip(options) {% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

Name type default description
animation boolean true apply a CSS fade transition to the tooltip
html boolean false Insert HTML into the tooltip. If false, jQuery's text method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement string | function 'top' how to position the tooltip - top | bottom | left | right | auto.
When "auto" is specified, it will dynamically reorient the tooltip. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right.
selector string false If a selector is provided, tooltip objects will be delegated to the specified targets.
title string | function '' default title value if title attribute isn't present
trigger string 'hover focus' how tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.
delay number | object 0

delay showing and hiding the tooltip (ms) - does not apply to manual trigger type

If a number is supplied, delay is applied to both hide/show

Object structure is: delay: { show: 500, hide: 100 }
container string | false false

Appends the tooltip to a specific element. Example: container: 'body'

Data attributes for individual tooltips

Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.

Markup

{% highlight html %} Hover over me {% endhighlight %}

Methods

$().tooltip(options)

Attaches a tooltip handler to an element collection.

.tooltip('show')

Reveals an element's tooltip.

{% highlight js %}$('#element').tooltip('show'){% endhighlight %}

.tooltip('hide')

Hides an element's tooltip.

{% highlight js %}$('#element').tooltip('hide'){% endhighlight %}

.tooltip('toggle')

Toggles an element's tooltip.

{% highlight js %}$('#element').tooltip('toggle'){% endhighlight %}

.tooltip('destroy')

Hides and destroys an element's tooltip.

{% highlight js %}$('#element').tooltip('destroy'){% endhighlight %}

Events

Event Type Description
show.bs.tooltip This event fires immediately when the show instance method is called.
shown.bs.tooltip This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.tooltip This event is fired immediately when the hide instance method has been called.
hidden.bs.tooltip This event is fired when the tooltip has finished being hidden from the user (will wait for CSS transitions to complete).
{% highlight js %} $('#myTooltip').on('hidden.bs.tooltip', function () { // do something… }) {% endhighlight %}

Popovers popover.js

Examples

Add small overlays of content, like those on the iPad, to any element for housing secondary information.

Plugin dependency

Popovers require the tooltip plugin to be included in your version of Bootstrap.

Popovers in button groups and input groups require special setting

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

Static popover

Four options are available: top, right, bottom, and left aligned.

Popover top

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Popover right

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Popover bottom

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Popover left

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Live demo

Click to toggle popover

Four directions

Usage

Enable popovers via JavaScript:

{% highlight js %}$('#example').popover(options){% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

Name type default description
animation boolean true apply a CSS fade transition to the tooltip
html boolean false Insert HTML into the popover. If false, jQuery's text method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement string | function 'right' how to position the popover - top | bottom | left | right | auto.
When "auto" is specified, it will dynamically reorient the popover. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right.
selector string false if a selector is provided, tooltip objects will be delegated to the specified targets if a selector is provided, tooltip objects will be delegated to the specified targets. in practice, this is used to enable dynamic HTML content to have popovers added. See this and an informative example.
trigger string 'click' how popover is triggered - click | hover | focus | manual
title string | function '' default title value if title attribute isn't present
content string | function '' default content value if data-content attribute isn't present
delay number | object 0

delay showing and hiding the popover (ms) - does not apply to manual trigger type

If a number is supplied, delay is applied to both hide/show

Object structure is: delay: { show: 500, hide: 100 }
container string | false false

Appends the popover to a specific element. Example: container: 'body'. This option is particularly useful in that it allows you to position the popover in the flow of the document near the triggering element - which will prevent the popover from floating away from the triggering element during a window resize.

Data attributes for individual popovers

Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.

Markup

For performance reasons, the Tooltip and Popover data-apis are opt in. If you would like to use them just specify a selector option.

Methods

$().popover(options)

Initializes popovers for an element collection.

.popover('show')

Reveals an elements popover.

{% highlight js %}$('#element').popover('show'){% endhighlight %}

.popover('hide')

Hides an elements popover.

{% highlight js %}$('#element').popover('hide'){% endhighlight %}

.popover('toggle')

Toggles an elements popover.

{% highlight js %}$('#element').popover('toggle'){% endhighlight %}

.popover('destroy')

Hides and destroys an element's popover.

{% highlight js %}$('#element').popover('destroy'){% endhighlight %}

Events

Event Type Description
show.bs.popover This event fires immediately when the show instance method is called.

Alert messages alert.js

Example alerts

Add dismiss functionality to all alert messages with this plugin.

Holy guacamole! Best check yo self, you're not looking too good.

Oh snap! You got an error!

Change this and that and try again. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras mattis consectetur purus sit amet fermentum.

Take this action Or do this

Usage

Enable dismissal of an alert via JavaScript:

{% highlight js %}$(".alert").alert(){% endhighlight %}

Markup

Just add data-dismiss="alert" to your close button to automatically give an alert close functionality.

{% highlight html %}{% endhighlight %}

Methods

$().alert()

Wraps all alerts with close functionality. To have your alerts animate out when closed, make sure they have the .fade and .in class already applied to them.

.alert('close')

Closes an alert.

{% highlight js %}$(".alert").alert('close'){% endhighlight %}

Events

Bootstrap's alert class exposes a few events for hooking into alert functionality.

Event Type Description
close.bs.alert This event fires immediately when the close instance method is called.
closed.bs.alert This event is fired when the alert has been closed (will wait for CSS transitions to complete).
{% highlight js %} $('#my-alert').bind('closed.bs.alert', function () { // do something… }) {% endhighlight %}

Buttons button.js

Example uses

Do more with buttons. Control button states or create groups of buttons for more components like toolbars.

Stateful

Add data-loading-text="Loading..." to use a loading state on a button.

{% highlight html %} {% endhighlight %}

Single toggle

Add data-toggle="button" to activate toggling on a single button.

{% highlight html %} {% endhighlight %}

Checkbox

Add data-toggle="buttons" to a group of checkboxes for checkbox style toggling on btn-group.

{% highlight html %}
{% endhighlight %}

Radio

Add data-toggle="buttons" to a group of radio inputs for radio style toggling on btn-group.

{% highlight html %}
{% endhighlight %}

Usage

Enable buttons via JavaScript:

{% highlight js %} $('.nav-tabs').button() {% endhighlight %}

Markup

Data attributes are integral to the button plugin. Check out the example code below for the various markup types.

Options

None

Methods

$().button('toggle')

Toggles push state. Gives the button the appearance that it has been activated.

Auto toggling

You can enable auto toggling of a button by using the data-toggle attribute.

{% highlight html %} {% endhighlight %}

$().button('loading')

Sets button state to loading - disables button and swaps text to loading text. Loading text should be defined on the button element using the data attribute data-loading-text.

{% highlight html %} {% endhighlight %}

Cross-browser compatibility

Firefox persists the disabled state across page loads. A workaround for this is to use autocomplete="off".

$().button('reset')

Resets button state - swaps text to original text.

$().button(string)

Resets button state - swaps text to any data defined text state.

{% highlight html %} {% endhighlight %}

Collapse collapse.js

About

Get base styles and flexible support for collapsible components like accordions and navigation.

Plugin dependency

Collapse requires the transitions plugin to be included in your version of Bootstrap.

Example accordion

Using the collapse plugin, we built a simple accordion by extending the panel component.

{% endhighlight %}

You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.

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

Usage

Via data attributes

Just add data-toggle="collapse" and a data-target to element to automatically assign control of a collapsible element. The data-target attribute accepts a CSS selector to apply the collapse to. Be sure to add the class collapse to the collapsible element. If you'd like it to default open, add the additional class in.

To add accordion-like group management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to see this in action.

Via JavaScript

Enable manually with:

{% highlight js %} $(".collapse").collapse() {% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-parent="".

parent selector false If selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this dependent on the accordion-group class)
toggle boolean true Toggles the collapsible element on invocation

Methods

.collapse(options)

Activates your content as a collapsible element. Accepts an optional options object. {% highlight js %} $('#myCollapsible').collapse({ toggle: false }) {% endhighlight %}

.collapse('toggle')

Toggles a collapsible element to shown or hidden.

.collapse('show')

Shows a collapsible element.

.collapse('hide')

Hides a collapsible element.

Events

Bootstrap's collapse class exposes a few events for hooking into collapse functionality.

Event Type Description
show.bs.collapse This event fires immediately when the show instance method is called.
shown.bs.collapse This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.collapse This event is fired immediately when the hide method has been called.
hidden.bs.collapse This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete).
{% highlight js %} $('#myCollapsible').on('hidden.bs.collapse', function () { // do something… }) {% endhighlight %}

Carousel carousel.js

The slideshow below shows a generic plugin and component for cycling through elements like a carousel.

{% highlight html %} {% endhighlight %}

Glyphicon Alternative

With Glyphicons available, you may choose to style the left and right toggle buttons with .glyphicon .glyphicon-chevron-left and .glyphicon .glyphicon-chevron-right.

Optional captions

Add captions to your slides easily with the .carousel-caption element within any .item. Place just about any optional HTML within there and it will be automatically aligned and formatted.

{% highlight html %}
...

{% endhighlight %}

Accessibility issue

The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.

Via data attributes

Use data attributes to easily control the position of the carousel. data-slide accepts the keywords prev or next, which alters the slide position relative to its current position. Alternatively, use data-slide-to to pass a raw slide index to the carousel data-slide-to="2", which shifts the slide position to a particular index beginning with 0.

Via JavaScript

Call carousel manually with:

{% highlight js %} $('.carousel').carousel() {% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-interval="".

Name type default description
interval number 5000 The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.
pause string "hover" Pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave.
wrap boolean true Whether the carousel should cycle continuously or have hard stops.

Methods

.carousel(options)

Initializes the carousel with an optional options object and starts cycling through items.

{% highlight js %} $('.carousel').carousel({ interval: 2000 }) {% endhighlight %}

.carousel('cycle')

Cycles through the carousel items from left to right.

.carousel('pause')

Stops the carousel from cycling through items.

.carousel(number)

Cycles the carousel to a particular frame (0 based, similar to an array).

.carousel('prev')

Cycles to the previous item.

.carousel('next')

Cycles to the next item.

Events

Bootstrap's carousel class exposes two events for hooking into carousel functionality.

Event Type Description
slide.bs.carousel This event fires immediately when the slide instance method is invoked.
slid.bs.carousel This event is fired when the carousel has completed its slide transition.
{% highlight js %} $('#myCarousel').on('slide.bs.carousel', function () { // do something… }) {% endhighlight %}

Affix affix.js

Example

The subnavigation on the left is a live demo of the affix plugin.

Usage

Via data attributes

To easily add affix behavior to any element, just add data-spy="affix" to the element you want to spy on. Then use offsets to define when to toggle the pinning of an element on and off.

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

Requires independent styling ;)

Affix toggles between three states/classes: affix, affix-top, and affix-bottom. You must provide the styles for these classes yourself (independent of this plugin). The affix-top class should be in the regular flow of the document. The affix class should be fixed to the page. And affix-bottom should be positioned absolute. Note, affix-bottom is special in that the plugin will place the element with JS relative to the offset: { bottom: number } option you've provided.

Via JavaScript

Call the affix plugin via JavaScript:

{% highlight js %} $('#myAffix').affix({ offset: { top: 100 , bottom: function () { return (this.bottom = $('.bs-footer').outerHeight(true)) } } }) {% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset-top="200".

Name type default description
offset number | function | object 10 Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and bottom directions. To provide a unique, bottom and top offset just provide an object offset: { top: 10 } or offset: { top: 10, bottom: 5 }. Use a function when you need to dynamically calculate an offset.
