<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). <ahref="{{ site.repo }}/blob/v{{ site.current_version }}/bower.json">Consult our <code>bower.json</code></a> to see which versions of jQuery are supported.</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>
<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>
<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>
<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>
<p>There are some caveats regarding using modals on mobile devices. <ahref="{{ page.base_url }}getting-started#mobile-modals">See our browser support docs</a> for details.</p>

<p>Be sure to add <code>role="dialog"</code> to <code>.modal</code>, <code>aria-labelledby="myModalLabel"</code> attribute to reference the modal title, and <code>aria-hidden="true"</code> to tell assistive technologies to skip the modal's DOM elements.</p>
<p>Additionally, you may give a description of your modal dialog with <code>aria-describedby</code> on <code>.modal</code>.</p>
<p>The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds <code>.model-open</code> to the <code><body></code> to override default scrolling behavior and generates a <code>.modal-backdrop</code> to provide a click area for dismissing shown modals when clicking outside the modal.</p>
<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>Manually toggles a modal. <strong>Returns to the caller before the modal has actually been shown or hidden</strong> (i.e. before the <code>shown.bs.modal</code> or <code>hidden.bs.modal</code> event occurs).</p>
<p>Manually opens a modal. <strong>Returns to the caller before the modal has actually been shown</strong> (i.e. before the <code>shown.bs.modal</code> event occurs).</p>
<p>Manually hides a modal. <strong>Returns to the caller before the modal has actually been hidden</strong> (i.e. before the <code>hidden.bs.modal</code> event occurs).</p>
<td>This event fires immediately when the <code>show</code> instance method is called. If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
<td>This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
<p>Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the <code>.open</code> class on the parent list item. When opened, the plugin also adds <code>.dropdown-backdrop</code> as a click area for closing dropdown menus when clicking outside the menu.</p>
<p>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.</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>Navbar links must have resolvable id targets. For example, a <code><a href="#home">home</a></code> must correspond to something in the DOM like <code><div id="home"></div></code>.</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 <ahref="{{ page.base_url }}components#nav-tabs">tab styling</a>, while adding the <code>nav</code> and <code>nav-pills</code> classes will apply <ahref="{{ page.base_url }}components#nav-pills">pill styling</a>.</p>
<p>To make tabs fade in, add <code>.fade</code> to each <code>.tab-pane</code>. The first tab pane must also have <code>.in</code> to properly fade in initial content.</p>
{% highlight html %}
<divclass="tab-content">
<divclass="tab-pane fade in active"id="home">...</div>
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>

<h4>Tooltips in button groups and input groups require special setting</h4>
<p>When using tooltips on elements within a <code>.btn-group</code> or an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).</p>
<p>To add a tooltip to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code><div></code> and apply the tooltip to that <code><div></code> instead.</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-animation=""</code>.</p>
<td>apply a CSS fade transition to the tooltip</td>
</tr>
<tr>
<td>html</td>
<td>boolean</td>
<td>false</td>
<td>Insert HTML into the tooltip. If false, jQuery's <code>text</code> method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.</td>
<td>how to position the tooltip - top | bottom | left | right | auto. <br> 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.</td>
<h4>Popovers in button groups and input groups require special setting</h4>
<p>When using popovers on elements within a <code>.btn-group</code> or an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).</p>
<p>To add a popover to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code><div></code> and apply the popover to that <code><div></code> instead.</p>
<ahref="#"class="btn btn-lg btn-danger"data-toggle="popover"title="A Title"data-content="And here's some amazing content. It's very engaging. right?"role="button">Click to toggle popover</a>

<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-animation=""</code>.</p>
<td>Insert HTML into the popover. If false, jQuery's <code>text</code> method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.</td>
<td>how to position the popover - top | bottom | left | right | auto.<br> 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.</td>
<td>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 <ahref="https://github.com/twbs/bootstrap/issues/4215">this</a> and <ahref="http://jsfiddle.net/fScua/">an informative example</a>.</td>
<p>Appends the popover to a specific element. Example: <code>container: 'body'</code>. 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.</p>
<p>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.</p>
<p>Wraps all alerts with close functionality. To have your alerts animate out when closed, make sure they have the <code>.fade</code> and <code>.in</code> class already applied to them.</p>
<p>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 <code>data-loading-text</code>.
<p><ahref="https://github.com/twbs/bootstrap/issues/793">Firefox persists the disabled state across page loads</a>. A workaround for this is to use <code>autocomplete="off"</code>.</p>

<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>
<h4>Transition animations not supported in Internet Explorer 8 & 9</h4>
<p>Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 & 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.</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>Use the affix plugin via data attributes or manually with your own JavaScript. <strong>In both situations, you must provide CSS for the positioning of your content.</strong></p>
<h3>Positioning via CSS</h3>
<p>The affix plugin toggles between three classes, each representing a particular state: <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) to handle the actual positions.</p>
<p>Here's how the affix plugin works:</p>
<ol>
<li>To start, the plugin adds <code>.affix-top</code> to indicate the element is in it's top-most position. At this point no CSS positioning is required.</li>
<li>Scrolling past the element you want affixed should trigger the actual affixing. This is where <code>.affix</code> replaces <code>.affix-top</code> and sets <code>position: fixed;</code> (provided by Bootstrap's code CSS).</li>
<li>If a bottom offset is defined, scrolling past that should replace <code>.affix</code> with <code>.affix-bottom</code>. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add <code>position: absolute;</code> when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.</li>
<p>To easily add affix behavior to any element, just add <code>data-spy="affix"</code> to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.</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-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 bottom 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>
