Administering the menu lists is easy once you get the hang of it.

Go to Administer>Site Building>Menus>List

This shows the list of menus on the site. They are arranged in blocks, for example the block called Navigation. Under navigation there is a list of all the menu items available.

Some menu items will be active, some will be 'inactive'.

Some will have parents, others wont.

Sorting the menu

This is done by clicking on the 'edit' link on each menu item and changing the Weight.

Applying a light weight makes the menu item float to the top of the list. Applying a heavier weight makes the menu item sink to the bottom.

In Drupal 6, this will be replaced by a drag-drop mechanism.

Each menu item has 3 options

Menus are simply links to resources on your own site or other places of the Internet.

In Drupal, menus are arranged into Blocks. You can manipulate blocks to that you can control where on the page your menu shows up.

There are 2 special menus, called Primary Links and Secondary links.  These normally contain the mot important links on your site. Quite often they are found at the top of your site pages.

These two menus are often themed - for instance some themes will style these menu items as tabs. 

You can control the behaviour of Primary and Secondary links in Administer>Site building>Menus>Settings.
