Select-like via ul – Approach 2 (working version)

Like all other form elements, a Select cannot include sub-elements, e.g. links or bold parts.
Example:

This file illustrates CSS specifications for a UL element to behave like a Select. Example:

This approach does not use a generated/given external-to-the-UL element for displaying the selected item:
the "1st LI" is used for that display (so the 1st "given LI" must be duplicated).
Other difference with the real Select: even when the "options" are hovered,
the selected option is kept highlighted (I like this reminder).
