One of the great things about using a framework such as DotNetNuke is that the pages exist independently of the skin that provides the look and feel of the site, including the menu. So, changing the skin will change the menu. The pages will not change at all.
If you need to change the page hierarchy, you do that on the Admin, Pages page. You can move the pages around using drag and drop. Again, the pages will not change -- only their relationship in the hierarchy changes. |
