navigation plugins & dropdown menus

I want a plugin that will create dropdown/flyout/etc menus for my navigation bars and possibly provide some other useful navigation tools. Preferably one that’s easy to use and requires little coding knowledge. I tried using the Multi-level Navigation plugin, but that did not work the way I wanted it to.

I’m brand new to wordpress, so that would be great if anyone can suggest any other good plugins to help improve functionality, ease of use, search engine optimization, and things of that sort. Thanks.
