- The Joomla core provides both a wrapper module and a wrapper menu item available by default. The purpose of the wrapper is to display content from a third party on your own website through the use of iframes. In later versions of Joomla, the menu item is referred to as an iframe wrapper.
While iframes aren't used nearly as much as they were in the past, they can still be useful in situations where you are trying to display either an entire website or multiple pages of an outside website while keeping your users on your own site. With an iframe wrapper, even the navigation of a third party website will be displayed within the module or content area.
