How to integrate more shortcodes into pages?

Hi, i understand you would like to have the Ad details page to have a left sidebar instead of right sidebar?

If so then please see “Custom Post Type Template” chapter here https://wpadverts.com/documentation/child-themes-and-templates/ it explains how to make a single-advert.php template that should look like the rest of your site, if this won’t work as expected you might need to ask your theme support about it, as how the single.php file works varies from theme to theme.
