You may have noticed you can add as many menus as you like to Wordpress. The best use for another one is to put it into the sidebar, as a widget. Say you have a list of pages which you don't want in the main menu bar, but you still want them visible to the visitor. You can simply add a new menu to Wordpress with your selected pages, posts or custom links and do this:

Appearance >> Widgets

And add a new Custom Menu Widget to the sidebar (to learn more about Widgets read this tutorial).

And that's it!

I hope you're now going to be making fantastically beautiful menus that have just what they need in them, in just the right order. Any questions, post them below.
