HI!
First of all thank you for your fast reply!
In fact I did explain it poorly! The screenshot provided by you is exactly the issue I am trying to solve.
Under the subject "Query" there are 2 sub-subjects "Information" and Products". We want to only show the sub-subjects when we click on "Query". More like a 2 Step Dropdown (I think within the customer service application it is that way)
Currently we see all subject values expanded like the screenshot provided by you shows.
Thanks!
