This is all which is required for basic usage.
Additional layer options:
For a more advanced use, Multiple choice layers also have extra settings which allow to set limits to how many items can and/or should be selected:
The setting “include in the total maximum items selected” works in conjunction with the setting “Maximum items per product”, found in Settings > Product Configurator > Multiple choice.
Global settings:
The global settings allow customising messages as well as the Maximum number of selected items per product, as mentioned above.
