How I can dependent parameters

[Pentargt85]

How can I make dependent parameters? So I wish that the data set of a parameter dependent of other parameter.

For example: In the first parameter drop down type the data set are: Europe, America and Asia, so if I choose Europe the second parameter should show only european countries.

And also if I choose Europe and American the second parameter should show european and american countries...

But I don't know how to do it....

Thanks in advance!

I came across a nice tutorial that gives an example of a cascading parameter in pentaho which sounds similar to what you are trying to do:
