<h3 id="js-individual-compiled">Individual or compiled</h3>
<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>
<div class="bs-callout bs-callout-danger">
<h4>Using the compiled JavaScript</h4>
<p>Both <code>bootstrap.js</code> and <code>bootstrap.min.js</code> contain all plugins in a single file. Include only one.</p>
</div>
<div class="bs-callout bs-callout-danger">
<h4>Component 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>
</div>
<div class="bs-callout bs-callout-danger">
<h4>Plugin dependencies</h4>
<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). <a href="https://github.com/twbs/bootstrap/blob/v3.2.0/bower.json">Consult our <code>bower.json</code></a> to see which versions of jQuery are supported.</p>
</div>
<h3 id="js-data-attrs">Data attributes</h3>
<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>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="nb">document</span><span class="p">).</span><span class="nx">off</span><span class="p">(</span><span class="s1">'.data-api'</span><span class="p">)</span></code></pre></div>
<p>Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="nb">document</span><span class="p">).</span><span class="nx">off</span><span class="p">(</span><span class="s1">'.alert.data-api'</span><span class="p">)</span></code></pre></div>
<h3 id="js-programmatic-api">Programmatic API</h3>
<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>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'.btn.danger'</span><span class="p">).</span><span class="nx">button</span><span class="p">(</span><span class="s1">'toggle'</span><span class="p">).</span><span class="nx">addClass</span><span class="p">(</span><span class="s1">'fat'</span><span class="p">)</span></code></pre></div>
<p>All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#myModal'</span><span class="p">).</span><span class="nx">modal</span><span class="p">()</span> <span class="c1">// initialized with defaults</span>
<span class="nx">$</span><span class="p">(</span><span class="s1">'#myModal'</span><span class="p">).</span><span class="nx">modal</span><span class="p">({</span> <span class="nx">keyboard</span><span class="o">:</span> <span class="kc">false</span> <span class="p">})</span> <span class="c1">// initialized with no keyboard</span>
<span class="nx">$</span><span class="p">(</span><span class="s1">'#myModal'</span><span class="p">).</span><span class="nx">modal</span><span class="p">(</span><span class="s1">'show'</span><span class="p">)</span> <span class="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>
<h4>Default settings</h4>
<p>You can change the default settings for a plugin by modifying the plugin's <code>Constructor.DEFAULTS</code> object:<p>
<div class="highlight"><pre><code class="language-js" data-lang="js"><span class="nx">$</span><span class="p">.</span><span class="nx">fn</span><span class="p">.</span><span class="nx">modal</span><span class="p">.</span><span class="nx">Constructor</span><span class="p">.</span><span class="nx">DEFAULTS</span><span class="p">.</span><span class="nx">keyboard</span> <span class="o">=</span> <span class="kc">false</span> <span class="c1">// changes default for the modal plugin's `keyboard` option to false</span></code></pre></div>
<h3 id="js-noconflict">No conflict</h3>
<p>Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call <code>.noConflict</code> on the plugin you wish to revert the value of.</p>
<div class="highlight"><pre><code class="js"><span class="kd">var</span> <span class="nx">bootstrapButton</span> <span class="o">=</span> <span class="nx">$</span><span class="p">.</span><span class="nx">fn</span><span class="p">.</span><span class="nx">button</span><span class="p">.</span><span class="nx">noConflict</span><span class="p">()</span> <span class="c1">// return $.fn.button to previously assigned value</span>
<span class="nx">$</span><span class="p">.</span><span class="nx">fn</span><span class="p">.</span><span class="nx">bootstrapBtn</span> <span class="o">=</span> <span class="nx">bootstrapButton</span> <span class="c1">// give $().bootstrapBtn the Bootstrap functionality</span></code></pre></div>
<h3 id="js-events">Events</h3>
<p>Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. <code>show</code>) is triggered at the start of an event, and its past participle form (ex. <code>shown</code>) is triggered on the completion of an action.</p>
<p>As of 3.0.0, all Bootstrap events are namespaced.</p>
<p>All infinitive events provide <code>preventDefault</code> functionality. This provides the ability to stop the execution of an action before it starts.</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#myModal'</span><span class="p">).</span><span class="nx">on</span><span class="p">(</span><span class="s1">'show.bs.modal'</span><span class="p">,</span> <span class="kd">function</span> <span class="p">(</span><span class="nx">e</span><span class="p">)</span> <span class="p">{</span>
<span class="k">if</span> <span class="p">(</span><span class="o">!</span><span class="nx">data</span><span class="p">)</span> <span class="k">return</span> <span class="nx">e</span><span class="p">.</span><span class="nx">preventDefault</span><span class="p">()</span> <span class="c1">// stops modal from being shown</span>
<span class="p">})</span></code></pre></div>
<h3 id="js-disabled">No special fallbacks when JavaScript is disabled</h3>
<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 <a href="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>
<div class="bs-callout bs-callout-warning" id="callout-third-party-libs">
<h4>Third-party libraries</h4>
<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>

<div class="bs-docs-section">
<h1 id="transitions" class="page-header">Transitions <small>transition.js</small></h1>
<h3>About transitions</h3>
<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>
<h3>What's inside</h3>
<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>

<h1 id="modals" class="page-header">Modals <small>modal.js</small></h1>
<p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p>
<div class="bs-callout bs-callout-warning" id="callout-stacked-modals">
<h4>Overlapping modals not supported</h4>
<p>Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.</p>
</div>
<div class="bs-callout bs-callout-warning" id="callout-modal-markup-placement">
<h4>Modal markup placement</h4>
<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>

<h4>Mobile device caveats</h4>
<p>There are some caveats regarding using modals on mobile devices. <a href="../getting-started/#support-fixed-position-keyboards">See our browser support docs</a> for details.</p>

<h2 id="modals-usage">Usage</h2>
<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>
<h3>Via data attributes</h3>
<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>
<div class="highlight"><pre><code class="html"><span class="nt"><button</span> <span class="na">type=</span><span class="s">"button"</span> <span class="na">data-toggle=</span><span class="s">"modal"</span> <span class="na">data-target=</span><span class="s">"#myModal"</span><span class="nt">></span>Launch modal<span class="nt"></button></span></code></pre></div>
<h3>Via JavaScript</h3>
<p>Call a modal with id <code>myModal</code> with a single line of JavaScript:</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#myModal'</span><span class="p">).</span><span class="nx">modal</span><span class="p">(</span><span class="nx">options</span><span class="p">)</span></code></pre></div>
<h3>Options</h3>
<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>

<h2 id="dropdowns-usage">Usage</h2>
<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. <strong class="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>
<h3>Via data attributes</h3>
<p>Add <code>data-toggle="dropdown"</code> to a link or button to toggle a dropdown.</p>
<div class="highlight"><pre><code class="html"><span class="nt"><div</span> <span class="na">class=</span><span class="s">"dropdown"</span><span class="nt">></span>

<h2 id="scrollspy-usage">Usage</h2>
<h3>Requires relative positioning</h3>
<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>.</p>
<h3>Via data attributes</h3>
<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>
<div class="highlight"><pre><code class="css"><span class="nt">body</span> <span class="p">{</span>
<span class="k">position</span><span class="o">:</span> <span class="k">relative</span><span class="p">;</span>
<span class="p">}</span></code></pre></div>
<div class="highlight"><pre><code class="html"><span class="nt"><body</span> <span class="na">data-spy=</span><span class="s">"scroll"</span> <span class="na">data-target=</span><span class="s">".navbar-example"</span><span class="nt">></span>

...
<span class="nt"></ul></span>
<span class="nt"></div></span>
...
<span class="nt"></body></span></code></pre></div>
<h3>Via JavaScript</h3>
<p>After adding <code>position: relative;</code> in your CSS, call the scrollspy via JavaScript:</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'body'</span><span class="p">).</span><span class="nx">scrollspy</span><span class="p">({</span> <span class="nx">target</span><span class="o">:</span> <span class="s1">'.navbar-example'</span> <span class="p">})</span></code></pre></div>
<div class="bs-callout bs-callout-danger">
<h4>Resolvable ID targets required</h4>
<p>Navbar links must have resolvable id targets. For example, a <code><a href="#home">home</a></code> must correspond to something in the DOM like <code><div id="home"></div></code>.</p>
</div>
<div class="bs-callout bs-callout-info">
<h4>Non-<code>:visible</code> target elements ignored</h4>
<p>Target elements that are not <a href="http://api.jquery.com/visible-selector/"><code>:visible</code> according to jQuery</a> will be ignored and their corresponding nav items will never be highlighted.</p>
</div>
<h3>Methods</h3>
<h4>.scrollspy('refresh')</h4>
<p>When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'[data-spy="scroll"]'</span><span class="p">).</span><span class="nx">each</span><span class="p">(</span><span class="kd">function</span> <span class="p">()</span> <span class="p">{</span>
<span class="kd">var</span> <span class="nx">$spy</span> <span class="o">=</span> <span class="nx">$</span><span class="p">(</span><span class="k">this</span><span class="p">).</span><span class="nx">scrollspy</span><span class="p">(</span><span class="s1">'refresh'</span><span class="p">)</span>
<span class="p">})</span></code></pre></div>
<h3>Options</h3>
<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>

<h4>Extends tabbed navigation</h4>
<p>This plugin extends the <a href="../components/#nav-tabs">tabbed navigation component</a> to add tabbable areas.</p>
</div>
<h2 id="tabs-usage">Usage</h2>
<p>Enable tabbable tabs via JavaScript (each tab needs to be activated individually):</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#myTab a'</span><span class="p">).</span><span class="nx">click</span><span class="p">(</span><span class="kd">function</span> <span class="p">(</span><span class="nx">e</span><span class="p">)</span> <span class="p">{</span>

<span class="p">})</span></code></pre></div>
<p>You can activate individual tabs in several ways:</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#myTab a[href="#profile"]'</span><span class="p">).</span><span class="nx">tab</span><span class="p">(</span><span class="s1">'show'</span><span class="p">)</span> <span class="c1">// Select tab by name</span>

<h3>Markup</h3>
<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 <a href="../components/#nav-tabs">tab styling</a>, while adding the <code>nav</code> and <code>nav-pills</code> classes will apply <a href="../components/#nav-pills">pill styling</a>.</p>

<h1 id="tooltips" class="page-header">Tooltips <small>tooltip.js</small></h1>
<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>

<h4>Opt-in functionality</h4>
<p>For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning <strong>you must initialize them yourself</strong>.</p>
</div>
<div class="bs-callout bs-callout-warning">
<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>
</div>
<div class="bs-callout bs-callout-warning">
<h4>Don't try to show tooltips on hidden elements</h4>
<p>Invoking <code>$(...).tooltip('show')</code> when the target element is <code>display: none;</code> will cause the tooltip to be incorrectly positioned.</p>
</div>
<div class="bs-callout bs-callout-info">
<h4>Tooltips on disabled elements require wrapper elements</h4>
<p>To add a tooltip to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code><div></code> and apply the tooltip to that <code><div></code> instead.</p>
</div>
<h2 id="tooltips-usage">Usage</h2>
<p>The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.</p>
<p>Trigger the tooltip via JavaScript:</p>
<div class="highlight"><pre><code class="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#example'</span><span class="p">).</span><span class="nx">tooltip</span><span class="p">(</span><span class="nx">options</span><span class="p">)</span></code></pre></div>
<h3>Markup</h3>
<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>
