Hierarchical table to drop down select menus

[johnforeman32]

Hi All,

I'm looking for an efficient way to translate an hierarchical table
into dynamic drop down select menus.

ie. Table is in the following form

Group Series Make
Model Code
--------- ---------
---------- ------------ --------
Fleet 4WD Ford
Explorer 01RW09338
Fleet 4WD Ford
Escape 01RW01111
Fleet 4WD GM
Ranger 663YY4444
Fleet Sedan Daewoo
Lanos 4443R3332

etc.

to the following dynamic drop down menus

Group [ Fleet v ]
Series [4WD v ]
Make [Ford v ]
Model [Explorer v]

My aim is to not go back to the server after each choice to determine
the contents of the subsequent menus. However my initial table
contains over 1000 rows and since I currently store the data in
javascript arrays at the point of creating the jsp, the load time of
the page is greatly affected
..
Does anyone have a better / more efficient solution?
