I came across an blocker, where I am trying to connect one form with two list. I am connecting the two list as ID(Primary Key) in Master List and MasterID(foreign key) in Child list. Now I am trying to access information by using the foreign key without using lookup. I want a drop down menu in my form which shows all the data related to a specific ID in the Master List. I know it is possible in onprem version but is it possible in Nintex for office 365 version as well?
Nintex for o365 supports cascading lookups if that's what you're referring to?
If not, can you supply a screenshot of what you are trying to achieve?
