Multiple Level Select In Html

I have a select box which runs a JavaScript when the option changes. Now I want to have multi level select, something like menus and submenus etc. What I want is like I have Optio

Solution 1:

There is jQuery plugin from Giva Labs called mcDropdown jQuery Plug-in v1.3.1, which serves similar purpose.
