I have menu with multiple level, but I want to display the B level menu with current menu root. Like if D1 is open then B3, B4 will visible. And, if A1 is opened then B1, B2 will visible and on B5 open B5 and B6 will visible.
A1 B1 B2 A2 B3 C1 C2 C3 D1 D2 B4 A3 B5 B6 A4
I tried the all possible settings but unable to do.
