Hi Torsten,
Do you mean it will look like this page? http://ja-university.demo.joomlart.com/index.php/en/explore/layouts/right-sidebar
If yes, you can go to template manager section, duplicate the default template style to have a new one called ‘JA University – Right sidebar’
Open this new template style > Navigate to ‘Layout’ tab > select ‘right-sidebar’ layout: http://prntscr.com/6g5lnb
Then in ‘Assignment’ tab, assign this style to the page you want.
Also notice that if you want to show ‘sidebar-1’ only, you should check the configuration of modules in ‘sidebar-2’ position and make sure that you don’t assign these modules to this page.
