CMS tutorial - Show functions
The Show button allows us to reveal details of the page that are normally hidden.
A zone is a container where editable items are held. There can be more than one zone on a page, depending on the page design. Use this function to reveal where the zones are - they will be shown as red boxes. Items can be moved from one zone to another using the Zone function under the Item button (see Item functions)
Items can not be deleted but can be removed from display by setting the visibility option to "hidden". This function un-hides them so that they can be recovered and edited if required.
