List Formatted Line Item-Dependent Drop Down
I have a line item which is list formatted, wherein end user selects a list item.
List: R3 Category List:
with a top level item "All Categories".
Problem: User is also able to select "All Categories", which is actually a top level item and should not be the case.
I know there is an option to remove top level using dependent dropdown for some reason the option is greyed out:
Thanks for the help.
