Subject RE: Expanding ADG to particular level
Date Mon, 05 May 2014 15:08:31 GMT
I am thinking of another solution:

Make displayItemsExpanded and
somehow expand it, which would make it expanded to 1st level folders,
since my ADG is 2 groups deep.
Is there a way to expand the ADG group programmatically?
