First drop down - will present the user Surname but in the table will be inserted Name. Drop down definition:
Second drop down - will present the user Alias and in the DB table it will be a number value.
Drop down definition:
Third dropdown - will present the user ID and will insert the ID to the DB table. Drop down definition:
Step 2 - Define the form:
We’ll use in this example table name “cascading”:
