Can this script be made into a multi-level menu?

I’ve been using this two-level menu on my site for a number of years, and like it because it’s easy to use, and I don’t have to update EVERY page of the website when I update the menu.

Now I have a need for a three-level menu, and have searched the internet for one that will work with my images…no luck finding one that works for me.

My question is: can this script be modified to make it three-level instead of two, or does anyone know of a similar script that can be easily updated like this one?

Thanks in advance for the help…y’all ALWAYS come through for me!

What type of menu, drop down menu?
If it is drop down then, I think there are ready made plugins.

I think this will help you.
