I have a matrix report with a bunch of nested groups. I am toggling one of the inner groups by placing a toggle item on its parent group... typical toggle item use.
When you do this you get "+" icon incidcating that the parent group can be expanded to reveal the child group. I happen to have chosen the initial view on the child to be hidden. So the "+" icon on the parent makes visual sense to tell the user that the group can be expanded. But when switch the intial view on the child to be NOT hidden, the toggle icon still appears as "+" icon.
How to I change this so that it appears as a "-" icon when I choose the intial view on the child to be expanded?
