Want to add a special sidebar to a specific page? There are several controls in this option area, the first of which is the creation of a new widget area. Here you’ll create the name of your new widget area, after you save your changes a new widget area appears in the widgets section in your WordPress dashboard. Create as many as you want. Within these widget areas you can add any widget you have available in your widgets section.
Something else that helps save you time and expands more possibilities is that each widget area you create is now found throughout the theme. For example: you create a page and want a specific sidebar for your page? Easy, in page options under where you write your content you just select your newly created widget area from a dropdown. This along with selecting a template with a right or left sidebar and you’ve done it. No coding needed.
You’ll also have the ability to alter sidebar positioning to either be fixed or scrolling. A feature that you can add sitewide or on a per page basis. If you want a little information in the sidebar to stay with the user as they scroll you can do it with a fixed sidebar.
