Trouble with jQuery dropdown - nested lists

I am trying to work on a jquery dropdown like the image attached. I am working on having the items below the word "Dog" each have a two col dropdown. Its not the CSS I cant get, its the logic of the menu.

I have an example of the XHTML markup below. That is the one for Dogs -> Foods.

Would the jQuery look something like this: (a member here, helped me out and to understanding this, great help.)

I guess I am really just having trouble with the selector to make it dynamic among the pattern.

Thank you,

Ryan
