Java EE (Java Enterprise Edition) General Discussion

Hi,

I only recently start reading JSF. My application need a multi-level drop-down menu bar pretty much like most windows app, e.g.

File Edit Options
- Open - Copy - Format Symbol -> Lines
- Close - Cut Rectangles
- Exit - Paste ...
----------- ...
- Search
- Replace

Say, on the menu bar, there are 3 main menu options: File, Edit, and Tools
1) when each top-level menu is selected, a drop-down menu is displayed with multiple entries for
selection
2) to bettr organize menu entries, sometimes a divider need to be used, e.g. between Paste and Search
in the Edit menu
3) menu entry may be disabled under certain condition, e.g. if nothing is copied or cut, then Paste should
be disabled
4) some menu entry when selected will display another drop down submenu.
e.g. when Tools -> Format Symbol is selected, a drop-down submenu is displayed next to the Format
Symbol to allow user to choose between Lines, Rectangles, etc.

Is there any built-in JSF component/renderer support any/all of these features?
If not, any open-source/commercial component/renderer available to do these?
If not, how can I build one myself?

Other more advanced features in mind are:
- checkbox/radio button associated with menu entry,
- context sensitive menu
- etc.

Thanks in advance
