To make sidebar fixed you need to add .left-sidebar-fixed class to the <body>

You can do it programmatically with javascript using our plugin. Call the fixedSidebar method with following parameters:

$('body').adminPlugin('fixedSidebar', true );

If you want to not be fixed anymore change true to false in method params.

$('body').adminPlugin('fixedSidebar', false );

You can play with it using buttons bellow. ( don`t forget to add content so you can scroll the page )

Sidebar status: Fixed
