Navmenu
Navmenu is a vertical navigation component. By default it shares it look and feel with the navmenu component.
Custom width
The navmenu is 300px wide by default. You can change this by customizing the @navmenu-width variable or by setting the width of .navmenu in your CSS.
Default navmenu
{% highlight html %}
{% endhighlight %}
Make navmenus accessible
Be sure to add a role="navigation" to every navmenu to help with accessibility.
Fixed to left or right
Add either .navmenu-fixed-left or .navmenu-fixed-right.
{% highlight html %}
{% endhighlight %}
Body padding required
The fixed navmenu will overlay your other content, unless you add padding to the left or right of the <body>. Try out your own values or use our snippet below. Tip: By default, the navmenu is 300px wide.
Make sure to include this after the Jasny Bootstrap CSS.
Off canvas
With the offcanvas plugin, you can hide the navmenu off canvas. This is especially useful for screens with a small viewport.
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis in aliquet nisl. Praesent sed leo congue, fringilla eros eu, tempus metus. Nam mollis odio ipsum, non vehicula ipsum accumsan sodales. Morbi varius vitae elit euismod cursus. Donec a dapibus justo, in facilisis nisi. Suspendisse ut turpis dui. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque dui risus, tincidunt at odio ut, ultrices dignissim ipsum. Cras ultrices erat nec leo luctus varius. Nulla sollicitudin tincidunt nulla, ut porta mauris volutpat vitae. Suspendisse ornare dolor sit amet massa venenatis pulvinar.
Modify the look of the navmenu by adding .navmenu-inverse.
{% highlight html %}
{% endhighlight %}
Alerts
Fixed to top / bottom
Add .alert-fixed-top top stick the alert on top of your page. Use .alert-fixed-bottom for the bottom.
Success! Your action has been completed successfully.
{% highlight html %}
Success! Your action has been completed successfully.
{% endhighlight %}
Buttons
Labels
Give a button some extra style by adding a label. Add .btn-labeled to any button with a label.
{% highlight html %}
{% endhighlight %}
Off canvas offcanvas.js
Example
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.
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis in aliquet nisl. Praesent sed leo congue, fringilla eros eu, tempus metus. Nam mollis odio ipsum, non vehicula ipsum accumsan sodales. Morbi varius vitae elit euismod cursus. Donec a dapibus justo, in facilisis nisi. Suspendisse ut turpis dui. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque dui risus, tincidunt at odio ut, ultrices dignissim ipsum. Cras ultrices erat nec leo luctus varius. Nulla sollicitudin tincidunt nulla, ut porta mauris volutpat vitae. Suspendisse ornare dolor sit amet massa venenatis pulvinar.
Add .offcanvas to hide an element. Alternatively add .offcanvas-* to hide an element up to a specific viewport width. Adding the .offcanvas class is not required. You may also hide an element by any other means.
The effect works best for elements positioned to the top, bottom, left or right of the window, either with absolute or fixed positioning.
When shown, the plugin adds .canvas-slid to the element that has slid.
Via data attributes
Add data-toggle="offcanvas" and a data-target to control, assigning it to show and hide the target element. The data-target attribute accepts a CSS selector to apply the collapse to.
Optionally add a data-canvas attribute to slide a canvas instead of only the target element. For a push menu set data-canvas="body".
Options can be placed both on control and on target menu element.
Name
type
default
description
canvas
string
false
If set, the canvas will be moved on show and hide instead of the target element. This creates alternative effects.
toggle
boolean
true
Toggles the off canvas element on invocation
placement
string
'auto'
Where to position the element at the start of the animation. For example, if placement is "left", the element will slide from left to right. The default option "auto" guesses the placement based on position and dimension.
autohide
boolean
true
Hide the off canvas element if clicked anywhere other that the element.
recalc
boolean
true
Calculate if off canvas should be disabled for this viewport width on window resize. If your elements always gets hidden on window resize, try setting this to false.
exclude
string
null
Set css selectors for elements, that have fixed positioning and that should not be moved when showing\hiding menu.
disableScrolling
boolean
true
Disable scrolling when the off canvas element is shown, by setting overflow to hidden for the body.
backdrop
boolean
false
If backdrop should be shown when menu is opened, in modal-like style.
Graceful degradation
For browsers that don't support transform (mainly IE8), the target option is ignored. In that case, the plugin will always slide the target element. In that case .canvas-slid will be added to the target element instead.
Two menus on the page
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 data-exclude option should be set for each menu, holding references to other menus. For example, if we have two menus #menu-left and #menu-right, then they should have the following option set, correspondingly: data-exclude="#menu-right" and data-exclude="#menu-left".
Methods
.offcanvas(options)
Initializes the off canvas element with an optional options.
.offcanvas('toggle')
Toggles an off canvas element to shown or hidden.

File input fileinput.js
Examples
The file input plugin allows you to create a visually appealing file or image input widgets.
In first of the following examples one can easily add support for file icon, how it previously was, untill Bootstrap dropped Glyphicons. Include the link to iconic font on the page, and replace the following line
{% highlight html %}
{% endhighlight %}
with the following (glyphicon classes should be changed to the ones that you use):
Image preview only works in IE10+, FF3.6+, Safari6.0+, Chrome6.0+ and Opera11.1+. In older browsers the filename is shown instead.
Usage
Add .fileinput to the container. Elements inside the container with .fileinput-new and .fileinput-exists are shown or hidden based on the current state. A preview of the selected file is placed in .fileinput-preview. The text of .fileinput-filename gets set to the name of the selected file.
Multiple file uploads can be handled by adding multiple attribute to file input element. Names of files are shown in name preview, joined by comma. In image preview only the first image is shown.
The file input widget should be placed in a regular <form> replacing a standard <input type="file">. The server side code should handle the file upload as normal.
Via data attributes
Add data-provides="fileinput" to the .fileinput element. Implement a button to clear the file with data-dismiss="fileinput". Add data-trigger="fileinput" to any element within the .fileinput widget to trigger the file dialog.
Via JavaScript
$('.fileinput').fileinput()
Layout
Using the given elements, you can layout the upload widget the way you want, either with a fixed width and height or with max-width and max-height.
