When you download and install “Divi Addon” a new section will be added to the Addons tab of Listdom -> Settings and you can ensure that this addon is installed successfully.
Now you can go to the Divi menu in the WordPress backend and click on the Theme Builder menu.
Then click on “Add New Template” link:
Then select the Listing option that you can create a template and click on Create Template.
Now you can create a custom body for the Listings with assigning different modules to the listing details page.
Finally the listings details page will be in the structure that you already designed in the Divi theme builder.
