Click on the item on the left, it will appear on the right.
Configure it, drag and drop it.

To add/configure GD Listings for the location page, use blocks or the shortcode builder. Add one GD Listings for each Custom Post Type.
Make sure the “Enable location filter” is checked, because the Location page is a template, and will be used for each individual location in your database.
