The Genesis Sample theme includes several widget areas that can be used to display content in various locations on your site.
Go to Appearance > Customize > Widgets to add widgets to the available widget areas in this theme.
The widget areas displayed in the customizer menu correspond with the page that is loaded in the interactive preview on the right side of the screen.
For example, the image below shows the Primary Sidebar and Footer 1 widget areas in the customizer menu because only those widget areas are available for display on the front page of the site. The After Entry widget area is not shown in the menu since that widget area is not displayed on the front page.
If we click on the Sample > Blog Post menu item inside the interactive preview, the After Entry widget area becomes available in the customizer menu since that widget area is displayed on single posts.
You can also access the available widget areas in this theme by going to Appearance > Widgets.
On the left side of the WP-Admin dashboard screen, you’ll see all the available widgets that you can add to your site. On the right side of the screen, you’ll see ALL of the available widget areas in this theme.
