It takes a while to understand how the menu system works. Here are a few tips:

Each menu item has a

• Title (the word/s which appear in the menu)
• Description (the phrase which appears when you hover over the menu item
• Path - if url aliases are enabled you can overwrite the default inserted by Drupal
• Expanded checkbox - if ticked, any child menu items will be displayed
• Parent dropdown
• Weight (-10 is highest, 10 is lowest in the sort order)

When you create a page you have a section where you can link the page to a menu item which will be created with the page. So be careful not to create a menu item and then create it again with the page!

It is possible (depending on theme) to place a menu in the left column outside a fixed width website (e.g. the Nokoala theme used in our Profect website) which is only visible to authenticated roles. Easiest is to place the Navigation menu block there, and create a separate menu for the Public menu links.
