This form shows the classification features linked to the part.

There are two types of features: configuration features and classification features.

A configuration feature is a feature for which options are available. For example, the feature 'Color' could have the options 'Red', 'White', and 'Black'. When a part is assigned the feature 'Color', configuration is required at order time, as the customer must choose the desired color.

A classification feature immediately specifies a part. The part might be a chair, and the feature is the color 'Black'. If the customer orders a black chair, he cannot choose any other color. Therefore, a classification feature has no options.
