<section id="components">
<h2>Components</h2>
<section id="componentModal">
<h3>Modal</h3>
<p>The <b>Modal</b> component works exactly as the original in most regards, with minor exceptions on options, events and public methods. It provides both an initialization option and a public method to write directly into your modal content.</p>
<p>In addition to adapting the spacing (padding) of the <code><body></code> elements like <code><nav class="navbar-fixed-top"></code> are also adapted in the same manner to get the smoothest possible transition. Like all components of the library, the component has the ability to provide access to the initialization even if your modal is setup via DATA API.</p>
<section id="modalOptions">
<h4>Options</h4>
<p>The <code>remote</code> option have been removed in Bootstrap 4 and we already replaced it with a better option. We also skipped the <code>show</code> option because via JavaScript we quickly and easily access
the component's public methods right after initialiation, we'll have a look in a minute.</p>
<div class="table-responsive">
<table class="table table-bordered table-striped js-options-table">
<thead>
<tr>
<th>Name</th>
<th>type</th>
<th>default</th>
<th>description</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>backdrop</code></td>
<td><em>boolean</em> or the <em>string</em> <code>'static'</code></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><code>keyboard</code></td>
<td><em>boolean</em></td>
<td>true</td>
<td>Option to dismiss the current modal via <kbd>Esc</kbd> key.</td>
</tr>
<tr>
<td><code>content</code></td>
<td><em>markup</em></td>
<td></td>
<td>The <b>Modal</b> component comes with a template system instead of a load <b>remote</b> content function (Bootstrap 4 drops it). This option can be used with JavaScript only.</td>
</tr>
</tbody>
</table>
</div>
<p>The default options' values are same as their jQuery plugin equivalents so you can expect same behavior.</p>
</section>
<section id="modalMethods">
<h4>Methods</h4>
<p>For further control the <b>Modal</b> component exposes a couple of public methods to be used via JavaScript :</p>
<div class="list-group">
<div class="list-group-item">
<h4 class="list-group-item-heading">.show()</h4>
<p class="list-group-item-text">The method that shows an initialized modal. When called, it will also hide any other visible modal before showing the one requested, making sure to keep the backdrop in place.</p>
</div>
<div class="list-group-item">
<h4 class="list-group-item-heading">.hide()</h4>
<p class="list-group-item-text">This hides an initialized modal. Additionally it will also close (if enabled) the backdrop.</p>
</div>
<div class="list-group-item">
<h4 class="list-group-item-heading">.toggle()</h4>
<p class="list-group-item-text">When called it shows the modal if hidden and hides it otherwise, using the above two methods.</p>
</div>
<div class="list-group-item">
<h4 class="list-group-item-heading">.setContent()</h4>
<p class="list-group-item-text">The method to enable you to set/override the content of <code><div class="modal-content"></code> element of your modal at any time, but you might want to avoid
using this method while the modal is animating.</p>
</div>
<div class="list-group-item">
<h4 class="list-group-item-heading">.update()</h4>
<p class="list-group-item-text">This allows you to update the modal layout (handling overflowing/non-overflowing body and/or modal) after you have changed it's content or other layout changes occured.
This would naturally follow the previous <code>.setContent()</code> method.</p>
</div>
</div>
</section>
<section id="modalEvents">
<h4>Events</h4>
<div class="table-responsive">
<table class="table table-bordered table-striped bs-events-table">
<thead>
<tr>
<th>Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>show.bs.modal</code></td>
<td>This event fires immediately when the <code>.show()</code> instance method is called. If caused by a click and the clicked element is a modal triggering element, that element is available
as the <code>event.relatedTarget</code> property of the event.</td>
</tr>
<tr>
<td><code>shown.bs.modal</code></td>
<td>This event is fired when the modal has been made visible to the user. The <code>event.relatedTarget</code> is same as for the above.</td>
</tr>
<tr>
<td><code>hide.bs.modal</code></td>
<td>This event is fired immediately when the <code>.hide()</code> instance method has been called.</td>
</tr>
<tr>
<td><code>hidden.bs.modal</code></td>
<td>This event is fired when the modal has finished being hidden from the user.</td>
</tr>
</tbody>
</table>
</div>
<p>The <code>loaded.bs.modal</code> original event is not needed, also because we replaced the <code>remote</code> option with another one. If modal is opened via JavaScript methods, or by clicking
on another element that is not a modal triggering element, the <code>relatedTarget</code> is <em>null</em>.</p>
</section>
<section id="modalUsage">
<h4>Usage</h4>
<h5 id="modalDataAPI">Via DATA API</h5>
<p>You can initialize <b>Modal</b> without writing any code as long as you have a modal and a trigger with <code>data-target</code> or a link with <code>href</code> referencing that modal. The component
will initialize for all elements with <code>data-toggle="modal"</code> found in the DOM.</p>
<pre><code class="language-markup"><!-- provide a trigger button -->
<button id="myModalTrigger" type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
<!-- Alternatively provide a link -->
<a id="myModalTrigger" data-toggle="modal" href="#myModal">Launch modal</a>
<!-- also the modal itself -->
<div id="myModal" class="modal fade" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
Some content
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</code></pre>
<p>The DATA API is suited for static content dialogs.</p>
<h5>Via JavaScript</h5>
<p>When you write your code, first make sure a modal template is present in the DOM. Generally you can initialize <b>Modal</b> for any instance of <code><div class="modal"></code> and immediately get access to methods. Alternativelly you can initialize on a triggering element, similar to how the DATA API works, in this case the <code>data-toggle="modal"</code> is not required, but you need to specify a modal reference via a specific attribute, like so <code><button data-target="#modalId"></code> or <code><a href="#modalId"></code>.</p>
<p>The JavaScript way is the <b>only</b> way to deal with dynamically added modals. Let's create a very basic modal template for the record.</p>
<pre><code class="language-markup"><!-- blank modal template -->
<div id="modalID" class="modal fade" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<!-- the .setContent() method will update this element's HTML -->
</div>
</div>
</div>
</code></pre>
<p>If you are looking for the functionality that grants you full control over your modal without the need of a triggering element, you can initialize that modal and get access to public methods right away:</p>
<pre><code class="language-javascript">// get the modal by ID
var myModal = document.getElementById('modalID');
// initialize on a <div class="modal"> with all options
// Note: options object is optional
var myModalInstance = new Modal(myModal,
{ // options object
content: '<div class="modal-body">Some content to be set on init</div>', // sets modal content
backdrop: 'static', // we don't want to dismiss Modal when Modal or backdrop is the click event target
keyboard: false // we don't want to dismiss Modal on pressing Esc key
});
// OR initialize and show the modal right away
var myModalInstance = new Modal(myModal, options);
myModalInstance.show();
// now you know why we don't need a show option
</code></pre>
<p>In other cases you can designate one or multiple triggering elements to open your modal, they will be the target of the constructor initialization and allow you to use same modal as a template to handle contents pushed by the triggering elements.</p>
<pre><code class="language-markup"><!-- <button> referencing the modal -->
<button type="button" id="buttonID" class="btn btn-primary" data-target="#modalID">My Button</button>
<!-- <a> referencing the modal -->
<a id="anchorID" class="btn btn-primary" href="#modalID">My Link</a>
</code></pre>
<p>Now let's initialize one of them right away:</p>
<pre><code class="language-javascript">// get a certain button trigger
var myButton = document.getElementById('buttonID');
// initiate Modal on a triggering element
var myModalInstance = new Modal(myButton,
{ // options object
content: '<div class="modal-body">Some content to be set on init</div>', // sets modal content
keyboard: false // we don't want to dismiss Modal on pressing Esc key
});
</code></pre>
<p>Now we have an initialization reference in <code>myModalInstance</code>, regardless of which element is the target of our constructor, we can start applying the component's public methods.</p>
<pre><code class="language-javascript">// show the modal at any time
myModalInstance.show();
// hide the modal
myModalInstance.hide();
// toggle the modal (show/hide)
myModalInstance.toggle();
// change the modal content
myModalInstance.setContent('<div class="modal-body">Some different content</div>');
// if the above method is used while modal was shown, you can then ask for a layout update
myModalInstance.update();
</code></pre>
<p>After initialization via DATA API or JavaScript, we also have access to the component's original events.</p>
<pre><code class="language-javascript">// GET THE EVENT TARGET, THE MODAL
// when we are certain which modal ID to work with
var myModal = document.getElementById('modalID');
// also button trigger related (especially when modals are targeted by multiple triggering elements)
// a triggering element is a link
var myModal = document.getElementById(myModalTriggerButton.getAttribute('href').replace('#',''));
// OR triggering element is not a link
var myModal = document.getElementById(myModalTriggerButton.getAttribute('data-target').replace('#',''));
// ATTACH HANDLERS
// show.bs.modal event
myModal.addEventListener('show.bs.modal', function(event){
// do something when this event triggers
// event.target is the modal referenced in myModal
// event.relatedTarget is the button referenced with myModalTriggerButton
}, false);
// shown.bs.modal event
myModal.addEventListener('shown.bs.modal', function(event){
// do something when this event triggers
// event.target is the modal referenced in myModal
// event.relatedTarget is the button referenced with myModalTriggerButton
}, false);
// hide.bs.modal event
myModal.addEventListener('hide.bs.modal', function(event){
// do something when this event triggers
// event.target is the modal referenced in myModal
}, false);
// hidden.bs.modal event
myModal.addEventListener('hidden.bs.modal', function(event){
// do something when this event triggers
// event.target is the modal referenced in myModal
}, false);
</code></pre>
<p>Additionally the component will store in the modal and it's triggering elements some references, for the internal execution, hopefully would help you as well. For instance, when a modal is referenced by one or more triggering elements, it will know which one was clicked last time to execute the <code>.show()</code> instance method.</p>
<pre><code class="language-javascript">// for modals with multiple triggering elements, the value changes every time the triggering element was clicked
var lastModalTrigger = myModal.modalTrigger;
</code></pre>
<p>Also each triggering element holds the initialization of the <b>Modal</b> component:</p>
<pre><code class="language-javascript">// when a modal was initialized via DATA API
// OR a triggering element is the target of the Modal constructor
var myModalInstance === document.getElementById('myModalTrigger').Modal;
</code></pre>
<p>These references are used internally to hide currently visible modals when showing another one. When the component is used via JavaScript only without a triggering element, you need to manually hide (via <code>.hide()</code> instance method) any visible modal before showing another modal (via the <code>.show()</code> instance method).</p>

<h5>Via JavaScript</h5>
<p>The following examples are focused on everything the <b>Modal</b> component offers for JavaScript initialization and usage. Given a modal template and some buttons to open the modal on click,
let's initialize it first:</p>
<pre><code class="language-javascript">// we grab a modal by ID
var myModal = document.getElementById('myModal');
// we grab some button by ID, we will use it later
var btnModal = document.getElementById('openModalViaJS');
// this button IS NOT a triggering element, as it has no reference to the above modal
// set a custom content
var firstModalContent = '<div class="modal-header">'
+'<button type="button" class="close" data-dismiss="modal" aria-label="Close">'
+'<span aria-hidden="true">×</span>'
+'</button>'
+'<h4 class="modal-title" id="myModalJSLabel">Modal title</h4>'
+'</div>'
+'<div class="modal-body">'
+'<p>This is where you fill up content you know, etc.</p>'
+'</div>'
+'<div class="modal-footer">'
+'<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>'
+'</div>';
// initialize Modal for this triggering element
var modalInitJS = new Modal(myModal, {
content: firstModalContent,
backdrop: 'static'
});
// OR initialize with no options provided
// the options obect is optional
var modalInitJS = new Modal(myModal);
// when we click btnModal, open the modal
btnModal.addEventListener('click', function(e){
modalInitJS.show();
}, false)
</code></pre>
<p>Here is what the above code does:</p>
<p><button id="openModalViaJS" type="button" class="btn btn-default btn-lg">Open Modal</button></p>
<p>Next we will initialize another triggering button, and attach a handler to it to change content of the modal when clicked.</p>
<pre><code class="language-javascript">// the reiggering element
var btnModal2 = document.getElementById('openModalViaJS2');
// set some custom content or get if from external sources
var externalModalContent = {
title: 'A modal title',
content: 'Modal content to fill the modal-body.',
};
// set a custom modal-content template
var secondModalContent =
'<div class="modal-header">'
+'<button type="button" class="close" data-dismiss="modal" aria-label="Close">'
+'<span aria-hidden="true">×</span>'
+'</button>'
+'<h4 class="modal-title" id="gridModalLabel">' + externalModalContent.title + '</h4>'
+'</div>'
+'<div class="modal-body">'
+'<p>' + externalModalContent.content + '</p>'
+'</div>'
+'<div class="modal-footer">'
+'<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>'
+'</div>';
// initialize Modal for this triggering element
var modalInitJS2 = new Modal(btnModal2, { backdrop: 'static' });
// now when we click this modal triggering element, we change the modal content
btnModal2.addEventListener('click', function() {
modalInitJS2.setContent(secondModalContent);
}, false);
</code></pre>
<p>By changing the <code>innerHTML</code> of the <code>modal-header</code>, <code>modal-body</code> or <code>modal-footer</code> with variables, you can achieve exactly the same as the
<a href="http://getbootstrap.com/javascript/#modals-related-target" target="_blank">other examples</a> from the demo of the original plugin. So we use same modal, but with different content:</p>
<p><a id="openModalViaJS2" class="btn btn-default btn-lg">Open Modal</a></p>
<p>Now if you go back to the previous triggering button and click it, you will notice that the modal is still like it was set by the second triggering button. Let's reset the modal content:</p>
<pre><code class="language-javascript">// we grab the button by ID
var btnModalNotTrigger = document.getElementById('modalNotTriggerJS');
// simply attach a click handler to it
btnModalNotTrigger.addEventListener('click', function() {
modalInitJS.setContent(firstModalContent); // revert modal content back to previous
modalInitJS.show(); // also show the modal
}, false);
</code></pre>
<p>Back to the previous modal content:</p>
<p><a id="modalNotTriggerJS" class="btn btn-default btn-lg" href="#">Reset</a></p>
<div id="myModalJS" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalJSLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
</div>
</div>
</div>
<p>Another example is using the <code>.update()</code> method. Let's say we have a modal initialized via DATA API, you might think we cannot access this instance's methods. Remember the trigger button
stores the initialization?</p>
<pre><code class="language-javascript">var modalUpdate = document.getElementById('modalUpdate'), // the trigger
anotherStaticModal = document.getElementById('anotherStaticModal'), // the modal
currentStaticModalBody = anotherStaticModal.querySelector('.modal-body'), // the body of the current modal
currentStaticModalBodyContent = currentStaticModalBody.innerHTML, // we cache the content of the body
modalUpdateInit = modalUpdate.Modal, // the initialization
changeModal1 = document.getElementById('changeModal1'), // the change buttons
changeModal2 = document.getElementById('changeModal2');
changeModal1.addEventListener('click', function(){
currentStaticModalBody.innerHTML = currentStaticModalBodyContent;
modalUpdateInit.update();
}, false);
changeModal2.addEventListener('click', function(){
currentStaticModalBody.innerHTML = '<h4>This modal changed via JavaScript</h4>';
currentStaticModalBody.innerHTML += '<p>Something you would want to be displayed in the body.</p>';
modalUpdateInit.update();
}, false);
</code></pre>

<h3>Dropdown</h3>
<p>The <b>Dropdown</b> component works like the original jQuery plugin and offers an additional option and an ability to handle click event in a way that you can create nested dropdowns and other cool stuff with ease.</p>
<p>Starting with version 2.0.20 the component supports some more robust accessibility features:</p>
<ul>
<li><kbd>Up</kbd> and <kbd>Down</kbd> arrow keys will users to select menu items, and also when pressed, the component will prevent default scroll behavior;</li>
<li><kbd>Esc</kbd> key will now close the dropdown, a feature previously supported, but reworked it's <code>keyHandler</code> to support the above new features, so it will close the last open nested dropdown element;</li>
<li><kbd>Enter</kbd> key will work as if click event triggered, the new event handler expectes the default browser behavior, let's hope it stays that way;</li>
<li>opening/closing the dropdown now it will focus the triggering button (on close) or the first focusable element from inside the dropdown menu (on open).</li>
</ul>
<section id="dropdownOptions">
<h4>Options</h4>

</div>
</div>
</section>
<section id="dropdownEvents">
<h4>Events</h4>
<p>Just like the original jQuery plugin, the <b>Dropdown</b> component covers this part as well:</p>
<div class="table-responsive">
<table class="table table-bordered table-striped bs-events-table">
<thead>
<tr>
<th>Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>show.bs.dropdown</code></td>
<td>This event fires immediately when the show instance method is called.</td>
</tr>
<tr>
<td><code>shown.bs.dropdown</code></td>
<td>This event is fired when the dropdown has been made visible to the user.</td>
</tr>
<tr>
<td><code>hide.bs.dropdown</code></td>
<td>This event is fired immediately when the hide instance method has been called.</td>
</tr>
<tr>
<td><code>hidden.bs.dropdown</code></td>
<td>This event is fired when the dropdown has finished being hidden from the user.</td>
</tr>
</tbody>
</table>
</div>
<p>The target of all component events is the parent <code><div class="dropdown"></code>, while the <code>event.relatedTarget</code> is the triggering element with the specific
<code>data-toggle="dropdown"</code> attribute. If you dismiss the dropdown via JavaScript, the <kbd>Esc</kbd> key or by clicking outside the triggering button, the <code>event.relatedTarget</code>
is <em>null</em>.</p>
</section>
<section id="dropdownUsage">
<h4>Usage</h4>
<h5>Via DATA API</h5>
<p>Notice we use same markup as the original example, the triggering element with the <code>data-toggle="dropdown"</code> attribute will initialize the <b>Dropdown</b> component.</p>
<pre><code class="language-markup"><!-- basic dropdown template -->
<div class="dropdown">
<button id="myDropdown" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown trigger
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="myDropdown">
...
</ul>
</div>
</code></pre>
<h5>Via JavaScript</h5>
<p>When you want full control or you need a way to handle dynamically generated dropdown-menus, you can do it via JavaScript. Considering the above HTML was inserted into the DOM, let's initialize it real quick:</p>
<pre><code class="language-javascript">// get some element that has the data-toggle="dropdown"
var myDropdown = document.getElementById('myDropdown');
// initialize component with it's 'persist' option
var myDropdownInit = new Dropdown( myDropdown, true );
// OR initialize component with no option
// the option is optional
var myDropdownInit = new Dropdown( myDropdown );
</code></pre>
<p>All right, now we have an initialization reference, we can get to work with the component's method:</p>
<pre><code class="language-javascript">// assuming the above, we can
myDropdownInit.toggle();
// or we can simply toggle the dropdown on initialization
var newDropdownInitialization = new Dropdown(myDropdown).toggle();
</code></pre>
<p>Also assuming the above HTML was used for your dropdown-menu, we can also attach the original events to the parent of the triggering element, which is the <code><div class="dropdown"></code> element:</p>
<pre><code class="language-javascript">// show.bs.dropdown
myDropdown.parentNode.addEventListener('show.bs.dropdown', function(event){
// do something when the event fires
// event.target is the PARENT of the triggering element
// event.relatedTarget is the triggering element
}, false);
// shown.bs.dropdown
myDropdown.parentNode.addEventListener('shown.bs.dropdown', function(event){
// do something when the event fires
// event.target is the PARENT of the triggering element
// event.relatedTarget is the triggering element
}, false);
// hide.bs.dropdown
myDropdown.parentNode.addEventListener('hide.bs.dropdown', function(event){
// do something when the event fires
// event.target is the PARENT of the triggering element
}, false);
// hidden.bs.dropdown
myDropdown.parentNode.addEventListener('hide.bs.dropdown', function(event){
// do something when the event fires
// event.target is the PARENT of the triggering element
}, false);
</code></pre>
<p>When your dropdown-menus have a different structure and the <code>myDropdown.parentNode</code> is NOT the <code><div class="dropdown"></code> element, you might consider a
<code>getClosest()</code> function to find it so you can then attach the original events to it.</p>
<p>Now, the <b>Dropdown</b> component also stores the initialization object in the targeted elements, just as for the modal triggering buttons:</p>
<pre><code class="language-javascript">// get some element we know it was initialized
var myDropdown = document.getElementById('myDropdown');
// reference the initialization
var myDropdownInit = myDropdown.Dropdown;
// use the public method
myDropdownInit.toggle();
</code></pre>
<p>Also you can do a simple check for the existence of <code>'Dropdown' in myDropdown</code> element to make sure you don't go the wrong way.</p>
</section>
<section id="dropdownExamples">
<h4>Examples</h4>
<p>Right out of the box, the above dropdown template is initialized via DATA-API right away.</p>
<div class="btn-group" style="margin-bottom:10px">
<div class="dropdown">
<button class="btn btn-primary" id="myDropdown" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown trigger <span class="caret"></span></button>
<ul class="dropdown-menu" aria-labelledby="myDropdown">
<li role="presentation"><a role="menuitem" href="#">Action</a></li>
<li role="presentation"><a role="menuitem" href="#">Another action</a></li>
<li role="presentation"><a role="menuitem" href="#">Something else here</a></li>
</ul>
</div>
</div>
<p>Ok now let's insert a new dropdown-menu and initialize right after via JavaScript.</p>
<pre><code class="language-javascript">// let's do it via a click handler to the following element
var makeMeDropdown = document.getElementById('makeMeDropdown');
// let's say we have a dropdown template as the above
// you may also reference one that you created yourself
var myDropdownTemplate = '<div class="dropdown">a valid template</div>';
makeMeDropdown.addEventListener('click', function(e){
e.preventDefault();
// don't do this again
if ( !/\bdisabled/.test(makeMeDropdown.className) ){
// invalidate the makeMeDropdown
this.setAttribute('disabled',true);
this.className = 'btn btn-default disabled';
this.innerHTML = 'All done';
// we inject the dropdown
this.parentNode.innerHTML += myDropdownTemplate;
// or use appendChild when myDropdownTemplate is an Element instance
// this.parentNode.appendChild( myDropdownTemplate );
// get a reference to the new dropdown
var formDropdown = document.getElementById('formDropdown');
// initiate with option
var DropdownInit = new Dropdown(formDropdown, true);
// also attach Dropdown original events
formDropdown.parentNode.addEventListener('show.bs.dropdown', function(e){
console.log('Do something when the event fires');
}, false);
formDropdown.parentNode.addEventListener('shown.bs.dropdown', function(e){
console.log('Do something when the event fires');
}, false);
formDropdown.parentNode.addEventListener('hide.bs.dropdown', function(e){
console.log('Do something when the event fires');
}, false);
formDropdown.parentNode.addEventListener('hidden.bs.dropdown', function(e){
console.log('Do something when the event fires');
}, false);
}
}, false);
</code></pre>
<p>That's all there is to do with <b>Dropdown</b> initialization, let's check a quick demo.</p>
<div class="btn-group" style="margin-bottom:10px">
<button id="makeMeDropdown" class="btn btn-success">Make me a Dropdown</button>
</div>
<p>A quick last example is with nested dropdown-menus, as the component will look for the child elements and will prevent itself from closing if the click target is a child item with <code>data-toggle</code> attribute.</p>
<ul class="nav nav-pills">
<li class="dropdown">

<h3>Scrollspy</h3>
<p>The <b>ScrollSpy</b> component inherits some of the <a href="http://getbootstrap.com/javascript/#scrollspy-usage" target="_blank">layout and other requirements</a> from the original jQuery plugin in some cases, while in other cases a special markup is required. The component offers public methods, the specific original event, and can be used with JavaScript as well as via DATA API.</p>
<p>The component will initialize for each element with <code>data-spy="scroll"</code> attribute, but will not work if the above requirements are not met or the anchors don't reference the containers accordingly.</p>
