Hello !

I'm developing a database interrogation user interface in XML/XSL with Cocoon.

The user having selected a request , the system generates a page on which he has to select
values for the requests' parameters .


For each single parameter, there is a number of values I select from the database through subrequests,
in order to generate a dropdown menu, for the user to choose between them.
All data for the subrequests' generation come from a XML file


There is never the same number of parameters , so I use a recursive template
to generate each subrequest


Is it possible to use the values selected from a thus generated menu ,
to modify the values proposed by another such menu, through a javascript function like 'Onchange'?


For example,
with two menus , 'Collection' and 'Types':

if I select collection number '1',
could it be possible to re-generate the following menu, so as to display only the types that are represented in the collection number '1'?


(I personally doubt this is possible, based on past experience)

What's your opinion?

Many thanks for every answer!!

Matt
