How can I show the top node in a selected hierarchy?

[hug_qlikview]

Hi,

I have a tree for the departments.

Example:

Cantonal Hospital

    dpt Pediatrics

      dpt Psychiatrics

In my application I would like to have a banner where I show the selected node. The problem is if I select dpt Pediatrics, implicitly I select all the "leaves" in this department which means that I have several selected values. How can I show (without selecting only one value) the top of the selected values?

Thanks,

Maria
