  <!-- Overview
  ================================================== -->
  <div class="bs-docs-section" id="js-overview">
    <div class="page-header">
      <h1>Overview</h1>
    </div>

    <h3 id="js-individual-compiled">Individual or compiled</h3>
    <p>Plugins can be included individually, or all at once. <strong>Do not attempt to include both.</strong> Both <strong>bootstrap.js</strong> and <strong>bootstrap.min.js</strong> contain all plugins in a single file.</p>
    <div class="bs-callout">
      <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.</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 body namespaced with <code>data-api</code>. This looks like this:
{% highlight js %}
$('body').off('.data-api')
{% endhighlight %}

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

    <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>
{% 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>
{% endhighlight %}

    <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>

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

    <h3 id="js-events">Events</h3>
    <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>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>
{% highlight js %}
$('#myModal').on('show.bs.modal', function (e) {
  if (!data) return e.preventDefault() // stops modal from being shown
})
{% endhighlight %}

    <div class="bs-callout" 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. Ask on the <a href="http://groups.google.com/group/twitter-bootstrap">mailing list</a> if you need help.</p>
    </div>
  </div>



  <!-- Transitions
  ================================================== -->
  <div class="bs-docs-section" id="transitions">
    <div class="page-header">
      <h1>Transitions <small>transition.js</small></h1>
    </div>
    <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&mdash;it's already there.</p>
    <h3>Use cases</h3>
    <p>A few examples of the transition plugin:</p>
    <ul>
      <li>Sliding or fading in modals</li>
      <li>Fading out tabs</li>
      <li>Fading out alerts</li>
      <li>Sliding carousel panes</li>
    </ul>

    <!-- Ideas: include docs for .fade.in, .slide.in, etc -->
  </div>



  <!-- Modal
  ================================================== -->
  <div class="bs-docs-section" id="modals">
    <div class="page-header">
      <h1>Modals <small>bootstrap-modal.js</small></h1>
    </div>

    <h2 id="modals-examples">Examples</h2>
    <p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p>

    <h3>Static example</h3>
    <p>A rendered modal with header, body, and set of actions in the footer.</p>

    <h2 id="modals-usage">Usage</h2>

    <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>
{% highlight html %}
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
{% endhighlight %}

    <h3>Via JavaScript</h3>
    <p>Call a modal with id <code>myModal</code> with a single line of JavaScript:</p>
    {% highlight js %}$('#myModal').modal(options){% endhighlight %}

    <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>
    <table class="table table-bordered table-striped">
      <thead>
       <tr>
         <th style="width: 100px;">Name</th>
         <th style="width: 50px;">type</th>
         <th style="width: 50px;">default</th>
         <th>description</th>
       </tr>
      </thead>
      <tbody>
       <tr>
         <td>backdrop</td>
         <td>boolean</td>
         <td>true</td>
         <td>Includes a modal-backdrop element. Alternatively, specify <code>static</code> for a backdrop which doesn't close the modal on click.</td>
       </tr>
       <tr>
         <td>keyboard</td>
         <td>boolean</td>
         <td>true</td>
         <td>Closes the modal when escape key is pressed</td>
       </tr>
       <tr>
         <td>show</td>
         <td>boolean</td>
         <td>true</td>
         <td>Shows the modal when initialized.</td>
       </tr>
       <tr>
         <td>remote</td>
         <td>path</td>
         <td>false</td>
         <td><p>If a remote URL is provided, content will be loaded via jQuery's <code>load</code> method and injected into the <code>.modal-body</code>. If you're using the data api, you may alternatively use the <code>href</code> tag to specify the remote source. An example of this is shown below:</p>
{% highlight html %}
<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>
{% endhighlight %}
       </tr>
      </tbody>
    </table>

    <h3>Methods</h3>

    <h4>.modal(options)</h4>
    <p>Activates your content as a modal. Accepts an optional options <code>object</code>.</p>
{% highlight js %}
$('#myModal').modal({
  keyboard: false
})
{% endhighlight %}

    <h4>.modal('toggle')</h4>
    <p>Manually toggles a modal.</p>
    {% highlight js %}$('#myModal').modal('toggle'){% endhighlight %}

    <h4>.modal('show')</h4>
    <p>Manually opens a modal.</p>
    {% highlight js %}$('#myModal').modal('show'){% endhighlight %}

    <h4>.modal('hide')</h4>
    <p>Manually hides a modal.</p>
    {% highlight js %}$('#myModal').modal('hide'){% endhighlight %}

    <h3>Events</h3>
    <p>Bootstrap's modal class exposes a few events for hooking into modal functionality.</p>
    <table class="table table-bordered table-striped">
      <thead>
       <tr>
         <th style="width: 150px;">Event Type</th>
         <th>Description</th>
       </tr>
      </thead>
      <tbody>
       <tr>
         <td>show</td>
         <td>This event fires immediately when the <code>show</code> instance method is called.</td>
       </tr>
       <tr>
         <td>shown</td>
         <td>This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete).</td>
       </tr>
       <tr>
         <td>hide</td>
         <td>This event is fired immediately when the <code>hide</code> instance method has been called.</td>
       </tr>
       <tr>
         <td>hidden</td>
         <td>This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).</td>
       </tr>
      </tbody>
    </table>
{% highlight js %}
$('#myModal').on('hidden.bs.modal', function () {
  // do something…
})
{% endhighlight %}
  </div>

          <h2>Usage</h2>

          <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>&lt;body&gt;</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>
{% highlight html %}
<body data-spy="scroll" data-target="#navbar-example">
  ...
</body>
{% endhighlight %}

          <h3>Via JavaScript</h3>
          <p>Call the scrollspy via JavaScript:</p>
{% highlight js %}
$('#navbar-example').scrollspy()
{% endhighlight %}

          <div class="bs-callout">
            <h4>Resolvable ID targets required</h4>
            <p>Navbar links must have resolvable id targets. For example, a <code>&lt;a href="#home"&gt;home&lt;/a&gt;</code> must correspond to something in the DOM like <code>&lt;div id="home"&gt;&lt;/div&gt;</code>.</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>
{% highlight js %}
$('[data-spy="scroll"]').each(function () {
  var $spy = $(this).scrollspy('refresh')
});
{% endhighlight %}


          <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>

          <h2>Usage</h2>
          <p>Enable tabbable tabs via JavaScript (each tab needs to be activated individually):</p>
{% highlight js %}
$('#myTab a').click(function (e) {
  e.preventDefault();
  $(this).tab('show');

{% endhighlight %}

          <p>You can activate individual tabs in several ways:</p>
{% 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 %}

          <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 tab styling.</p>
{% highlight html %}

        <div class="page-header">
          <h1>Popovers <small>bootstrap-popover.js</small></h1>
        </div>

        <h2>Examples</h2>
        <p>Add small overlays of content, like those on the iPad, to any element for housing secondary information. Hover over the button to trigger the popover.</p>

        <div class="bs-callout">
          <h4>Plugin dependency</h4>
          <p>Popovers require the <a href="#tooltips">tooltip plugin</a> to be included in your version of Bootstrap.</p>

        <div class="bs-callout">
          <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>
        </div>

        <h3>Static popover</h3>

            <h2>Usage</h2>

            <h3>Via data attributes</h3>
            <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>

            <h3>Via JavaScript</h3>
            <p>Enable manually with:</p>
{% highlight js %}
$(".collapse").collapse()
{% endhighlight %}

            <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-parent=""</code>.</p>

            <h2>Usage</h2>

            <h3>Via data attributes</h3>
            <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>

            <h3>Via JavaScript</h3>
            <p>Call carousel manually with:</p>
{% highlight js %}
$('.carousel').carousel()
{% endhighlight %}

            <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-interval=""</code>.</p>

{% endhighlight %}

            <h4>.carousel('cycle')</h4>
            <p>Cycles through the carousel items from left to right.</p>

            <h4>.carousel('pause')</h4>
            <p>Stops the carousel from cycling through items.</p>


            <h4>.carousel(number)</h4>
            <p>Cycles the carousel to a particular frame (0 based, similar to an array).</p>

            <h4>.carousel('prev')</h4>
            <p>Cycles to the previous item.</p>

            <h4>.carousel('next')</h4>
            <p>Cycles to the next item.</p>

          <!-- Affix
          ================================================== -->
          <section id="affix">
            <div class="page-header">
              <h1>Affix <small>bootstrap-affix.js</small></h1>
            </div>

            <h2>Example</h2>
            <p>The subnavigation on the left is a live demo of the affix plugin.</p>

            <hr class="bs-docs-separator">

            <h2>Usage</h2>

            <h3>Via data attributes</h3>
            <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>

{% highlight html %}
<div data-spy="affix" data-offset-top="200">...</div>
{% endhighlight %}

            <div class="bs-callout">
              <h4>Requires positioning</h4>
              <p>You must manage the position of a pinned element and the behavior of its immediate parent. Position is controlled by <code>affix</code>, <code>affix-top</code>, and <code>affix-bottom</code>. Remember to check for a potentially collapsed parent when the affix kicks in as it's removing content from the normal flow of the page.</p>
            </div>

            <h3>Via JavaScript</h3>
            <p>Call the affix plugin via JavaScript:</p>
{% highlight js %}
$('#navbar').affix()
{% endhighlight %}

            <h3>Methods</h3>
            <h4>.affix('refresh')</h4>
            <p>When using affix in conjunction with adding or removing of elements from the DOM, you'll want to call the refresh method:</p>
{% highlight js %}
$('[data-spy="affix"]').each(function () {
  $(this).affix('refresh')
});
{% endhighlight %}

          <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-top="200"</code>.</p>

          <table class="table table-bordered table-striped">
            <thead>
             <tr>
               <th style="width: 100px;">Name</th>
               <th style="width: 100px;">type</th>
               <th style="width: 50px;">default</th>
               <th>description</th>
             </tr>
            </thead>
            <tbody>
             <tr>
               <td>offset</td>
               <td>number | function | object</td>
               <td>10</td>
               <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 listen for a single direction, or multiple unique offsets, just provide an object <code>offset: { x: 10 }</code>. Use a function when you need to dynamically provide an offset (useful for some responsive designs).</td>
