Infinite Assignments - Never ending value lists
When simple related value lists just aren't enough, you have to come up with a solution that allows for the assignment of a hierarchy of values. The trick is creating a method which limits any subsequent selection to staying within the hierarchy of the parent selection. You may be working with the classification of organisms or tracking all the various parts that make up a computer circuit board. Whatever the task is, there may be a need for infinite assignments.
Working off of what we learned in Infinite Hierarchies, we can create a system which is not only structurally correct, but allows for an infinite level of flexibility!
