This is two different ways to create sub-menus in Udo, depending on your needs. The first is to use a page as the branch point, this means users can visit the menu, and the sub menu items, as distinct pages. The alternative way is to attach a menu and a sub-menu, with pages attached to the sub-menu, this prevents the menu item from having its own dedicated page.
Example:
Main Menu (menu)
- Home (page)
- Products (page)
- Category A (category)
- Categeory B (category)
- About Us (menu)
- Company Profile (page)
- Our Services (page)
- Why Choose Us. (page)
- Contact Us (page)
In the above example visitors are able to see your Product landing area, to help the customer decide which category they want. However visitors are automatically directed to Company Profile when someone tries to visit the About Us menu link, because it is not a page.
