Best simple css drop down menu

[Lex$]

Does anyone know of any really simple CSS drop down menus which also have multiple drop downs? The ones I have found are terrible to put into existing websites.

E.g.

Dropdown One

• Navigation Item 1
• Navigation Item 2
  
  • Navigation Item 1
  • Navigation Item 2
  • Navigation Item 3
  • Navigation Item 4
  • Navigation Item 5
  
  
• Navigation Item 3
  
  • Navigation Item 1
  • Navigation Item 2
  • Navigation Item 3
