A sidebar hides additional content beside a page.




A sidebar

Although sidebars can be used with any content, in most cases, sidebars are used with inverted vertical menu. Please see the usage tab for more details.

<body> <div class="ui sidebar inverted vertical menu"> <a class="item"> 1 </a> <a class="item"> 2 </a> <a class="item"> 3 </a> </div> <div class="pusher"> <!-- Site content !--> </div> </body>
$('.ui.sidebar') .sidebar('toggle') ;
<div class="ui left demo vertical inverted sidebar labeled icon menu"> <a class="item"> <i class="home icon"></i> Home </a> <a class="item"> <i class="block layout icon"></i> Topics </a> <a class="item"> <i class="smile icon"></i> Friends </a> </div>
$('.ui.labeled.icon.sidebar') .sidebar('toggle') ;




A sidebar can be visible on the page

To have a sidebar appear on page load simply add the class visible to the sidebar.



A pusher can be dimmed



A sidebar can appear on different sides of the page


A sidebar can specify its width

A sidebar will automatically adjust its animations to match any custom size specified in CSS


Page Structure

Using a sidebar requires a specific page structure. For optimal performance your page should be already set-up with this structure before initializing a sidebar.

Sidebar will automatically add the correct layout on first load if it is not set-up, however fixing your page's layout on load will reduce performance and is not recommended.
<body> <div class="ui sidebar"> ... </div> <div class="pusher"> Your site's actual content </div> </body>

Using with Menu

Sidebars can be any content, however the most common type of content to display off-canvas is a menu. To understand the required structure for a menu, please refer to the menu documentation.

<body> <div class="ui left vertical menu sidebar"> <a class="item"> Item 1 </a> <a class="item"> Item 2 </a> <a class="item"> Item 3 </a> </div> <div class="pusher"> <!-- Site content !--> </div> </body>

Using Fixed Content

Any fixed position content that should move with page content when your sidebar is visible, should receive the class name fixed and exist as a sibling element to your sidebar.

Fixed content that is not included adjacent to your pusher will lose its positioning when a sidebar is shown.
<body> <div class="ui sidebar"> ... </div> <div class="ui top fixed menu"> ... </div> <div class="pusher"> Your site's actual content </div> </body>

iOS Sidebars

Sidebars use a special fix for iOS that are added using userAgent detection.

This should have no meaningful affect on your code, but will prevent the canvas from incorrectly autoresizing when a sidebar opens.

html.ios { overflow-x: hidden; -webkit-overflow-scrolling: touch; } html.ios, html.ios body { height: initial !important; }


All the following behaviors can be called using the syntax:

$('.your.element') .sidebar('behavior name', argumentOne, argumentTwo) ;
Behavior Description
attach events(selector, event) Attaches sidebar action to given selector. Default event if none specified is toggle
show Shows sidebar
hide Hides sidebar
toggle Toggles visibility of sidebar
is visible Returns whether sidebar is visible
is hidden Returns whether sidebar is hidden
push page Pushes page content to be visible alongside sidebar
get direction Returns direction of current sidebar
pull page Returns page content to original position
add body CSS Adds stylesheet to page head to trigger sidebar animations
remove body CSS Removes any inline stylesheets for sidebar animation
get transition event Returns vendor prefixed transition end event



Not all sidebar transitions are available for every sidebar direction, or when multiple sidebars are visible at a time.

Displaying Multiple

Multiple sidebars can be displayed at the same time only when using a supported animation like push or overlay.

You may need to manually set the z-index on elements to ensure the intended sidebar element appears on top.
If you are triggering multiple sidebars at the same time, its recommended to set the transition to overlay.
// showing multiple $('.demo.sidebar') .sidebar('setting', 'transition', 'overlay') .sidebar('toggle') ;

Using a custom context

A sidebar can be initialized inside any element, not just a page's body.

A sidebar's context cannot have any padding. You can solve this by padding its inner content, or using an additional containing element
// using context $('.context.example .ui.sidebar') .sidebar({ context: $('.context.example .bottom.segment') }) .sidebar('attach events', '.context.example .menu .item') ;

Triggering show/hide with other content

For convenience calling attach events will allow you to bind events. By default this will toggle the sidebar in and out of view on click

$('.left.demo.sidebar').first() .sidebar('attach events', '.toggle.button') ; $('.toggle.button') .removeClass('disabled') ;
Trigger Sidebar

Triggering custom behavior with other content

You can also specify what behavior should occur when the element is clicked

$('.left.demo.sidebar').first() .sidebar('attach events', '.open.button', 'show') ; $('.open.button') .removeClass('disabled') ;
Open Sidebar

Starting Visible

A sidebar can start visible by adding the class name visible

You must include the class pushable on a sidebars containing element for it to appear correctly before Javascript initializes the element
Although sidebars support any size content, sidebars that are visible on load only support standard, predefined sizes like thin or wide. This makes sure content can be positioned correctly before Javascript is available.
// showing multiple $('.visible.example .ui.sidebar') .sidebar({ context: '.visible.example .bottom.segment' }) .sidebar('hide') ;
