I like to make my CSS menus from scratch, but if you want to save yourself some time here are a couple of resources you should know about.

First, is the classic Listamatic and Listamatic 2. Those two resources alone will give you enough to start building all types of menus. There is sample code for simple vertical and horizontal menus, nested list menus, nested popup list menus and the list is endless. With so many choices it can be hard to decide which CSS list menu you should choose to tweak for your website.

If you want to do as little tweaking as possible, I recently came across CSS Menu Maker. While there are not a ton of choices for menus, with a couple of clicks you can have everything you need, including images, to add to your website. Fill in the form and you will be presented with a download link to download the CSS, HTML and images to use on your website. It does not get much easier than that.

Now you have no excuse not to use CSS and lists for your menus.
