Is it possibility to show the report in a grid based on group type?

is this a paging grid? create a rule named something like rule!showUsersFromGroupInGrid(), and pass in one group as a parameter. In the grid text column you'd call apply(rule!showUsersFromGroupInGrid, local!listOfGroups).

In the rule, declare a local variable "users" and populate it with the members of the passed-in group. Then have it output: joinArray(local!users, char(10)) - to join the list of usernames with a linebreak in between each one.
