Control sidebar is the right sidebar. It can be used for many purposes and is extremely easy to create. The sidebar ships with two different show/hide styles. The first allows the sidebar to slide over the content. The second pushes the content to make space for the sidebar. Either of these methods can be set through the [JavaScript options]({% link javascript/control-sidebar.md %}).
Once you create the sidebar, you will need a toggle button to open/close it. By adding the attribute data-toggle="control-sidebar" to any button, it will automatically act as the toggle button.
