The product demonstrates updating the Product Code (model) by the module depending on selected options.

If any combination of related options is selected, the module changes the Product Code (model) to the model of the selected combination.

The product also demonstrates the situation when the module feature named "Reset options" can be required. 

For example, it is possible to select "Capacity" - "four persons" and "Color" - "Green". But then it is not possible to change the selection (select other option values), because selected "Capacity" value limits the available values of "Color" and, at the same time, selected "Color" limits available values of "Capacity". Thus, reset the option is only the way to select another combination of option values.

As another solution the option type "Select" can be used (this option type has the always-available pseudo-value "--- Please Select ---").
