Complex Conditional Metadata depends on what are +called "behaviours". Essentially, behaviours are assigned to a single +field, and can contain any number of values that are available in that field. Each field +can have multiple behaviours assigned to it.
+ +Each behaviour can cause a number of other behaviours — in +the field's child fields — to become available. By assigning values +to behaviours, and creating relationships between behaviours, you can create extremely complex +relationships between available lookup values.
