The sidebar appears to the right of the mainbody section. In this case, the sidebar is a Lists RokSprocket widget.
Here is the widget breakdown for the Sidebar section:
The Gantry Extras widget located in the sidebar section of the page is a RokSprocket Lists widget created in a very similar way to the previous RokSprocket widgets featured on the front page of the demo.
First, you will need to create the RokSprocket Widget. You can do this by navigating to Administration -> RokSprocket Admin and creating a new Lists widget.
Here is a look at the Lists Layout Options for this widget.

Previews Per Page
You can set the RokSprocket filters to include any category, specific posts, or otherwise you would like to have featured in this widget.
Once you have created this widget, you can add it via the Widgets menu by clicking RokSprocket and dragging it to the appropriate section. When you have done this, you will need to complete the following.
Set the Title to Gantry Extras
Select your RokSprocket Lists widget in the Choose Widget field.
Set the Title Variation field to Title 1.
Leaving everything else at its default setting, select Save.
The widget should now be created and ready for use on the front page of your WordPress site.
