About Hidden Attributes
When you place a check mark in the Hidden field in an attribute definition, the attribute does not display in the Quote, Order, Agreement, or Asset views. For example, if you assign a product to a class that has hidden attribute A1. When you add this product to a quote and select Dynamic Attributes, A1 does not display.
The attribute continues to display in customizable product selection pages and you can write configuration rules on it.
Use hidden attributes to create configuration parameters that customers do not need to see. For example, you could define a hidden attribute whose value is the number of bays required for a chassis. You could then write configuration rules that use the value of this attribute to monitor the number of available bays during a configuration session.
