#16 new vertical menu style - vertical open and close

[Gert Van den Eynde]

Hi,

Would it be difficult to add the following style: a vertical menu that
when the mouse hovers over a menu item at level 1 splits open
just below this item and shows the 2nd level corresponding to this
item below with a small indent? And this for several levels deep...

Example

Entry 1
Entry 2
Entry 3

Hover on Entry 2 gives

Entry 1
Entry 2
Entry 2.1
Entry 2.2
Entry 3

When the mouse leaves the area between Entry 2 and Entry 3,
the menu folds shut again to the initial state?

Thanks,

gert
