Menu Help - Organizing by Group

I am looking to layout an menu based on groups as following:

- item1
- item2
- group1
- item3
- item4
- item5

It looks like I have to create a new page called group1 with no content just so I can have item3 and item4 as submenus.

Is there a better way to do this?

Ideally, if I click on group1, it would display a page with links to item3 and item4. that page would be generated by building the menu not by editing the page content.

cheers,
Warner
