Visual representation of a Matrix

Hey,

I have the following scenario ( Not sure if it would be possible to do this, but just a luck!)

I have 2 matrices: One has the hierarchy Hem -> Region -> Area to Country. The other one has Div -> PSL -> Sub

(I am just showing with the first hierearchy for ease)

So My matrix looks like this:

I will be publishing it as it looks to everyone. But I need it to be visually appealing in the following way:

1. When a person chooses a Region Filter, then the visual highlights those areas that come under it as well (Given that no region is chosen, it will look as the above matric, Given that a region is chosen, then it will look as follows)

As you can see, I have chosen AP in the region filter, and then i clicked on the "+" icon to further show the areas. But I want this to automatically happen, some one choses a region filter.

-> Similarly, for the other matrix, when someone chooses a PSL, it should automatically show the Sub under it. If not chose, it would look like the default view.

 Any help? Thank You!
