<!-- Overview

================================================== -->

<div class="bs-docs-section">

<div class="page-header">

<h1 id="js-overview">Overview</h1>

</div>

<h3 id="js-individual-compiled">Individual or compiled</h3>

<p>Plugins can be included individually (using Jasny Bootstrap's individual <code>*.js</code> files), or all at once (using <code>jasny-bootstrap.js</code> or the minified <code>jasny-bootstrap.min.js</code>).</p>

<p>The Jasny Bootstrap plugins work with or without loading vanilla Bootstrap's <code>bootstrap.js</code>.</p>

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

<h4>Do not attempt to include both.</h4>

<p>Both <code>jasny-bootstrap.js</code> and <code>jasny-bootstrap.min.js</code> contain all plugins in a single file.</p>

</div>

<h3 id="js-data-attrs">Data attributes</h3>

<p>You can use all Jasny 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:

{% highlight js %}

$(document).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 %}

$(document).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 %}

$(".fileinput").fileinput().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 %}

$("#myMenu").offcanvas() // initialized with defaults

$("#myMenu").offcanvas({ autohide: false }) // initialized with no autohide

$("#myMenu").offcanvas('show') // initializes and invokes show immediately</p>

{% endhighlight %}

<p>Each plugin also exposes its raw constructor on a <code>Constructor</code> property: <code>$.fn.popover.Offcanvas</code>. If you'd like to get a particular plugin instance, retrieve it directly from an element: <code>$('.navmenu').data('offcanvas')</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 3.1.2, 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 %}

$('#myMenu').on('show.bs.offcanvas', function (e) {

if (!data) return e.preventDefault() // stops menu from being shown

})

{% endhighlight %}

</div>

<!-- Off canvas

================================================== -->

<div class="bs-docs-section">

<div class="page-header">

<h1 id="offcanvas">Off canvas <small>offcanvas.js</small></h1>

</div>

<h2 id="offcanvas-examples">Example</h2>

<p>The offcanvas plugin allows you to hide an element from sight and than show it by moving either that or any other element. It's intended to be used for off canvas navigation, like push menus.</p>

<div class="bs-example bs-navmenu-offcanvas-example">

<div id="myNavmenuCanvas">

<nav id="myNavmenu" class="navmenu navmenu-default navmenu-fixed-left offcanvas" role="navigation">

<a class="navmenu-brand" href="#">Brand</a>

<ul class="nav navmenu-nav">

<li class="active"><a href="#">Home</a></li>

<li><a href="#">Link</a></li>

<li><a href="#">Link</a></li>

</ul>

</nav>

<div class="navbar navbar-default navbar-fixed-top">

<button type="button" class="navbar-toggle" data-toggle="offcanvas" data-target="#myNavmenu" data-canvas="#myNavmenuCanvas" data-placement="left">

<h4>Examples</h4>

<p>For better understanding, have a look at the <a href="../examples/navmenu/">off canvas slide in menu</a>, <a href="../examples/navmenu-push/">off canvas push menu</a> and <a href="../examples/navmenu-reveal/">off canvas reveal menu</a> examples.</p>

</div>

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

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

<p>Add <code>.offcanvas</code> to hide an element. Alternatively add <code>.offcanvas-*</code> to hide an element up to a specific viewport width. Adding the <code>.offcanvas</code> class is not required. You may also hide an element by any other means.</p>

<p>The effect works best for elements positioned to the top, bottom, left or right of the window, either with absolute or fixed positioning.</p>

<p>When shown, the plugin adds <code>.canvas-slid</code> to the element that has slid.</p>

<h3>Via data attributes</h3>

<p>Add <code>data-toggle="offcanvas"</code> and a <code>data-target</code> to control, assigning it to show and hide the target element. The <code>data-target</code> attribute accepts a CSS selector to apply the collapse to.</p>

<p>Optionally add a <code>data-canvas</code> attribute to slide a canvas instead of only the target element. For a push menu set <code>data-canvas="body"</code>.

<h3>Via JavaScript</h3>

<p>Call the input mask via javascript:</p>

{% highlight js %}

$('.navmenu').offcanvas()

{% endhighlight %}

<h3>Options</h3>

<p>Options can be placed both on control and on target menu element.</p>

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

<h4>Graceful degradation</h4>

<p>For browsers that don't support transform (mainly IE8), the <code>target</code> option is ignored. In that case, the plugin will always slide the target element. In that case <code>.canvas-slid</code> will be added to the target element instead.</p>

</div>

<h3>Two menus on the page</h3>

<p>If there are two (or more) menus on the page, there can be only one opened at a time. When menu attempts to be opened, already opened one will be closed first. It's almost fully automated, accept that <code>data-exclude</code> option should be set for each menu, holding references to other menus. For example, if we have two menus <code>#menu-left</code> and <code>#menu-right</code>, then they should have the following option set, correspondingly: <code>data-exclude="#menu-right"</code> and <code>data-exclude="#menu-left"</code>.</p>

<h3>Methods</h3>

<h4>.offcanvas(options)</h4>

<p>Initializes the off canvas element with an optional options.</p>

<h4>.offcanvas('toggle')</h4>

<p>Toggles an off canvas element to shown or hidden.</p>

<h4>.offcanvas('show')</h4>
