drill down map and switch to coolers based on different variable

[Anonymous]

Hi

here is the qvf file in the attachment.

hope any one can help with find a solution to find out how to create a drill down solution on map object (I do not have access to geo_map service)

Some detail:

there is on hierarchy--- County- municipality 

I hope I can have this drill down function on the map any suggestion?

I create the master drill down item but it does not work

so I create 2 layers but now : I show all the level at the same time ---which is also not I want

I only have really municipality level data in on County, which I want to drill down.
