<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="https://github.com/twbs/bootstrap/blob/v3.3.5/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>
<h4>Only one plugin per element via data attributes</h4>
<p>Don't use data attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To accomplish this, use a wrapping element.</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>
<divclass="highlight"><pre><codeclass="language-js"data-lang="js"><spanclass="nx">$</span><spanclass="p">(</span><spanclass="s1">'#myModal'</span><spanclass="p">).</span><spanclass="nx">modal</span><spanclass="p">()</span><spanclass="c1">// initialized with defaults</span>
<spanclass="nx">$</span><spanclass="p">(</span><spanclass="s1">'#myModal'</span><spanclass="p">).</span><spanclass="nx">modal</span><spanclass="p">({</span><spanclass="na">keyboard</span><spanclass="p">:</span><spanclass="kc">false</span><spanclass="p">})</span><spanclass="c1">// initialized with no keyboard</span>
<spanclass="nx">$</span><spanclass="p">(</span><spanclass="s1">'#myModal'</span><spanclass="p">).</span><spanclass="nx">modal</span><spanclass="p">(</span><spanclass="s1">'show'</span><spanclass="p">)</span><spanclass="c1">// initializes and invokes show immediately</span></code></pre></div>
<p>Each plugin also exposes its raw constructor on a <code>Constructor</code> property: <code>$.fn.popover.Constructor</code>. If you'd like to get a particular plugin instance, retrieve it directly from an element: <code>$('[rel="popover"]').data('popover')</code>.</p>
<divclass="highlight"><pre><codeclass="language-js"data-lang="js"><spanclass="nx">$</span><spanclass="p">.</span><spanclass="nx">fn</span><spanclass="p">.</span><spanclass="nx">modal</span><spanclass="p">.</span><spanclass="nx">Constructor</span><spanclass="p">.</span><spanclass="nx">DEFAULTS</span><spanclass="p">.</span><spanclass="nx">keyboard</span><spanclass="o">=</span><spanclass="kc">false</span><spanclass="c1">// changes default for the modal plugin's `keyboard` option to false</span></code></pre></div>
<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>
<spanclass="nx">$</span><spanclass="p">.</span><spanclass="nx">fn</span><spanclass="p">.</span><spanclass="nx">bootstrapBtn</span><spanclass="o">=</span><spanclass="nx">bootstrapButton</span><spanclass="c1">// give $().bootstrapBtn the Bootstrap functionality</span></code></pre></div>
<p>Bootstrap provides custom events for most plugins' 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 triggered on the completion of an action.</p>
<p>As of 3.0.0, all Bootstrap events are namespaced.</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>
<spanclass="k">if</span><spanclass="p">(</span><spanclass="o">!</span><spanclass="nx">data</span><spanclass="p">)</span><spanclass="k">return</span><spanclass="nx">e</span><spanclass="p">.</span><spanclass="nx">preventDefault</span><spanclass="p">()</span><spanclass="c1">// stops modal from being shown</span>
<p>The version of each of Bootstrap's jQuery plugins can be accessed via the <code>VERSION</code> property of the plugin's constructor. For example, for the tooltip plugin:</p>
<p>Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user experience in this case, use <ahref="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/noscript"><code><noscript></code></a> to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.</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.</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>Transitions can be globally disabled using the following JavaScript snippet, which must come after <code>transition.js</code> (or <code>bootstrap.js</code> or <code>bootstrap.min.js</code>, as the case may be) has loaded:</p>
<p>Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.</p>
<p>There are some caveats regarding using modals on mobile devices. <ahref="../getting-started/#support-fixed-position-keyboards">See our browser support docs</a> for details.</p>
<p><strongclass="text-danger">Due to how HTML5 defines its semantics, the <code>autofocus</code> HTML attribute has no effect in Bootstrap modals.</strong> To achieve the same effect, use some custom JavaScript:</p>
<p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
<h4>Popover in a modal</h4>
<p>This <ahref="#"role="button"class="btn btn-default popover-test"title="A Title"data-content="And here's some amazing content. It's very engaging. right?">button</a> should trigger a popover on click.</p>

<p>Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. <ahref="https://stackoverflow.com/questions/18622508/bootstrap-3-and-youtube-in-modal">See this helpful Stack Overflow post</a> for more information.</p>
<h2id="modals-grid-system">Using the grid system</h2>
<p>To take advantage of the Bootstrap grid system within a modal, just nest <code>.container-fluid</code> within the <code>.modal-body</code> and then use the normal grid system classes within this container.</p>
<h2id="modals-related-target">Varying modal content based on trigger button</h2>
<p>Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use <code>event.relatedTarget</code> and <ahref="https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes">HTML <code>data-*</code> attributes</a> (possibly <ahref="http://api.jquery.com/data/">via jQuery</a>) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on <code>relatedTarget</code>,</p>

<p>The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds <code>.modal-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>
<p><strongclass="text-danger">This option is deprecated since v3.3.0 and will be removed in v4.</strong> We recommend instead using client-side templating or a data binding framework, or calling <ahref="http://api.jquery.com/load/">jQuery.load</a> yourself.</p>
<p>If a remote URL is provided, <strong>content will be loaded one time</strong> via jQuery's <code>load</code> method and injected into the <code>.modal-content</code> div. 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>
</tr>
<tr>
<td>shown.bs.modal</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>
</tr>
<tr>
<td>hide.bs.modal</td>
<td>This event is fired immediately when the <code>hide</code> instance method has been called.</td>
</tr>
<tr>
<td>hidden.bs.modal</td>
<td>This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).</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.</p>
<p>On mobile devices, opening a dropdown adds a <code>.dropdown-backdrop</code> as a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. <strongclass="text-danger">This means that switching from an open dropdown menu to a different dropdown menu requires an extra tap on mobile.</strong></p>
<p>Note: The <code>data-toggle="dropdown"</code> attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.</p>
<h4><code>data-toggle="dropdown"</code> still required</h4>
<p>Regardless of whether you call your dropdown via JavaScript or instead use the data-api, <code>data-toggle="dropdown"</code> is always required to be present on the dropdown's trigger element.</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>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>
<h4>Non-<code>:visible</code> target elements ignored</h4>
<p>Target elements that are not <ahref="http://api.jquery.com/visible-selector/"><code>:visible</code> according to jQuery</a> will be ignored and their corresponding nav items will never be highlighted.</p>
<p>No matter the implementation method, scrollspy requires the use of <code>position: relative;</code> on the element you're spying on. In most cases this is the <code><body></code>. When scrollspying on elements other than the <code><body></code>, be sure to have a <code>height</code> set and <code>overflow-y: scroll;</code> applied.</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>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=""</code>.</p>
<p>Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus. <strong>Nested tabs are not supported.</strong></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.

<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>

<p>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.</p>
<p>Tooltips with zero-length titles are never displayed.</p>

<p>The required markup for a tooltip is only a <code>data</code> attribute and <code>title</code> on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to <code>top</code> by the plugin).</p>
<divclass="highlight"><pre><codeclass="language-html"data-lang="html"><spanclass="c"><!-- HTML to write --></span>
<spanclass="nt"><a</span><spanclass="na">href=</span><spanclass="s">"#"</span><spanclass="na">data-toggle=</span><spanclass="s">"tooltip"</span><spanclass="na">title=</span><spanclass="s">"Some tooltip text!"</span><spanclass="nt">></span>Hover over me<spanclass="nt"></a></span>
<spanclass="c"><!-- Generated markup by the plugin --></span>
<p>Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>
<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>
<h4>Don't try to show tooltips on hidden elements</h4>
<p>Invoking <code>$(...).tooltip('show')</code> when the target element is <code>display: none;</code> will cause the tooltip to be incorrectly positioned.</p>
<h4>Accessible tooltips for keyboard and assistive technology users</h4>
<p>For users navigating with a keyboard, and in particular users of assistive technologies, you should only add tooltips to keyboard-focusable elements such as links, form controls, or any arbitrary element with a <code>tabindex="0"</code> attribute.</p>
<h4>Tooltips on disabled elements require wrapper elements</h4>
<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>

<p>Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using <ahref="#tooltips-options">the <code>selector</code> option</a>) cannot be individually destroyed on descendant trigger elements.</p>
<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>
<h4>Don't try to show popovers on hidden elements</h4>
<p>Invoking <code>$(...).popover('show')</code> when the target element is <code>display: none;</code> will cause the popover to be incorrectly positioned.</p>
<h4>Popovers on disabled elements require wrapper elements</h4>
<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>
<p>Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>

<p>Be sure to add <code>aria-expanded</code> to the control element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of <code>aria-expanded="false"</code>. If you've set the collapsible element to be open by default using the <code>in</code> class, set <code>aria-expanded="true"</code> on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.</p>
<p>Additionally, if your control element is targetting a single collapsible element – i.e. the <code>data-target</code> attribute is pointing to an <code>id</code> selector – you may add an additional <code>aria-controls</code> attribute to the control element, containing the <code>id</code> of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.</p>
<p>Just add <code>data-toggle="collapse"</code> and a <code>data-target</code> to the 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 a selector is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the <code>panel</code> class)</td>
<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>
<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>Carousels require the use of an <code>id</code> on the outermost container (the <code>.carousel</code>) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's <code>id</code>, be sure to update the relevant controls.</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>The <code>data-ride="carousel"</code> attribute is used to mark a carousel as animating starting at page load. <strongclass="text-danger">It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.</strong></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>The affix plugin toggles <code>position: fixed;</code> on and off, emulating the effect found with <ahref="https://developer.mozilla.org/en-US/docs/Web/CSS/position#Sticky_positioning"><code>position: sticky;</code></a>. The subnavigation on the right is a live demo of the affix plugin.</p>
<p>Use the affix plugin via data attributes or manually with your own JavaScript. <strongclass="text-danger">In both situations, you must provide CSS for the positioning and width of your affixed content.</strong></p>
<p>Note: Do not use the affix plugin on an element contained in a relatively positioned element, such as a pulled or pushed column, due to a <ahref="https://github.com/twbs/bootstrap/issues/12126">Safari rendering bug</a>.</p>
<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, with the exception of <code>position: fixed;</code> on <code>.affix</code>, for these classes yourself (independent of this plugin) to handle the actual positions.</p>
<li>To start, the plugin adds <code>.affix-top</code> to indicate the element is in its 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 CSS).</li>
<li>If a bottom offset is defined, scrolling past it 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>
<p>Recalculates the state of the affix based on the dimensions, position, and scroll position of the relevant elements. The <code>.affix</code>, <code>.affix-top</code>, and <code>.affix-bottom</code> classes are added to or removed from the affixed content according to the new state. This method needs to be called whenever the dimensions of the affixed content or the target element are changed, to ensure correct positioning of the affixed content.</p>
