Cascading Filter for logged in user caller and L2, L3, L4, L5

[Guru6]

Need to have a Cascading Filter based on the logged in user (for ex: incident.caller) with the respective user's L2, L3, L4, L5 to get selected.

• If you are the caller and no more users under you, it should appear single inputs for L2, L3, L4, L5 as only one input the caller.
  • The 1st field should be Self with logged in user (javascript:gs.getUserName())
  • 2nd field should be L2, logged in user.L2 (single user)
  • 3rd field should be L3, logged in user.L3 (single user)
  • 4th field should be L4, logged in user.L4 (single user)
  • 5th field should be L5, logged in user.L5 (single user)

• If you are the caller (like L2, L3, L4, L5) and more users under you, it should appear multiple inputs for L2, L3, L4, L5 based on the assigned list
  • The 1st field should be Self with logged in user (javascript:gs.getUserName()), can be L2/L3/L4/L5.
  • If logged in user is L2, Self should be L2 user, L2 should be selectable with only one L2 user (logged in user), L3 users, L4 users, L5 users, users to be selectable.
  • Similarly for L3, L4, L5 as well.

Please advise on this.

Thanks,

Guru.
