<p>Plugins can be included individually (using Bootstrap's individual <code>*.js</code> files), or all at once (using <code>bootstrap.js</code> or the minified <code>bootstrap.min.js</code>).</p>
<p>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 <strong>before</strong> the plugin files).</p>
<p>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.</p>
<p>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 <code>data-api</code>. This looks like this:
<p>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.</p>
{% highlight js %}
$(".btn.danger").button("toggle").addClass("fat")
{% endhighlight %}
<p>All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):</p>
{% highlight js %}
$("#myModal").modal() // initialized with defaults
$("#myModal").modal({ keyboard: false }) // initialized with no keyboard
$("#myModal").modal('show') // initializes and invokes show immediately</p>
<p>Each plugin also exposes its raw constructor on a <code>Constructor</code> property: <code>$.fn.popover.Constructor</code>. If you'd like to get a particular plugin instance, retrieve it directly from an element: <code>$('[rel=popover]').data('popover')</code>.</p>
<p>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 <code>.noConflict</code> on the plugin you wish to revert the value of.</p>
{% highlight js %}
var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
<p>Bootstrap provides custom events for most plugin's unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. <code>show</code>) is triggered at the start of an event, and its past participle form (ex. <code>shown</code>) is trigger on the completion of an action.</p>
<p>All infinitive events provide <code>preventDefault</code> functionality. This provides the ability to stop the execution of an action before it starts.</p>
<p><strong>Bootstrap does not officially support third-party JavaScript libraries</strong> like Prototype or jQuery UI. Despite <code>.noConflict</code> and namespaced events, there may be compatibility problems that you need to fix on your own. Ask on the <ahref="http://groups.google.com/group/twitter-bootstrap">mailing list</a> if you need help.</p>
<p>For simple transition effects, include <code>transition.js</code> once alongside the other JS files. If you're using the compiled (or minified) <code>bootstrap.js</code>, there is no need to include this—it's already there.</p>
<p>Transition.js is a basic helper for <code>transitionEnd</code> 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.</p>

Be sure to add <code>role="dialog"</code> to your primary modal div. In the example above, <code>div#myModal</code>.<br>
Also, the <code>aria-labelledby</code> attribute references your modal title. In this example, <code>h4#myModalLabel</code>.<br>
Finally, <code>aria-hidden="true"</code> tells assistive technologies to skip DOM elements.<br>
Additionally, you may give a description of your modal dialog. Use the <code>aria-describedby</code> attribute in the modal's primary <code><div></code> to point to this description (this is not shown in the above example).
<p>Activate a modal without writing JavaScript. Set <code>data-toggle="modal"</code> on a controller element, like a button, along with a <code>data-target="#foo"</code> or <code>href="#foo"</code> to target a specific modal to toggle.</p>
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-backdrop=""</code>.</p>
<td><p>If a remote URL is provided, content will be loaded via jQuery's <code>load</code> method and injected into the root of the modal element. If you're using the data api, you may alternatively use the <code>href</code> attribute to specify the remote source. An example of this is shown below:</p>

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

<p>You can activate a tab or pill navigation without writing any JavaScript by simply specifying <code>data-toggle="tab"</code> or <code>data-toggle="pill"</code> on an element. Adding the <code>nav</code> and <code>nav-tabs</code> classes to the tab <code>ul</code> will apply the Bootstrap tab styling.</p>
Activates a tab element and content container. Tab should have either a <code>data-target</code> or an <code>href</code> targeting a container node in the DOM.
<td>This event fires on tab show, but before the new tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
<td>This event fires on tab show after a tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>

<p>Just add <code>data-toggle="collapse"</code> and a <code>data-target</code> to element to automatically assign control of a collapsible element. The <code>data-target</code> attribute accepts a CSS selector to apply the collapse to. Be sure to add the class <code>collapse</code> to the collapsible element. If you'd like it to default open, add the additional class <code>in</code>.</p>
<p>To add accordion-like group management to a collapsible control, add the data attribute <code>data-parent="#selector"</code>. Refer to the demo to see this in action.</p>
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-parent=""</code>.</p>
<td>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 <code>accordion-group</code> class)</td>
<p>With <ahref="{{ site.glyphicons }}">Glyphicons</a> available, you may choose to style the left and right toggle buttons with <code>.glyphicon .glyphicon-chevron-left</code> and <code>.glyphicon .glyphicon-chevron-right</code>.</p>
<p>Add captions to your slides easily with the <code>.carousel-caption</code> element within any <code>.item</code>. Place just about any optional HTML within there and it will be automatically aligned and formatted.</p>
<p>The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.</p>
<p>Use data attributes to easily control the position of the carousel. <code>data-slide</code> accepts the keywords <code>prev</code> or <code>next</code>, which alters the slide position relative to its current position. Alternatively, use <code>data-slide-to</code> to pass a raw slide index to the carousel <code>data-slide-to="2"</code>, which shifts the slide position to a particular index beginning with <code>0</code>.</p>
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-interval=""</code>.</p>
<p>To easily add affix behavior to any element, just add <code>data-spy="affix"</code> to the element you want to spy on. Then use offsets to define when to toggle the pinning of an element on and off.</p>
Affix toggles between three states/classes: <code>affix</code>, <code>affix-top</code>, and <code>affix-bottom</code>. You must provide the styles for these classes yourself (independent of this plugin).
The <code>affix-top</code> class should be in the regular flow of the document. The <code>affix</code> class should be fixed to the page. And <code>affix-bottom</code> should be positioned absolute. Note, <code>affix-bottom</code> is special in that the plugin will place the element with JS relative to the <code>offset: { bottom: number }</code> option you've provided.
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-offset-top="200"</code>.</p>
<td>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 left directions. To provide a unique, bottom and top offset just provide an object <code>offset: { top: 10 }</code> or <code>offset: { top: 10, bottom: 5 }</code>. Use a function when you need to dynamically calculate an offset.</td>
