In Deepser, lists are organized data groups that can be used as options for custom, system fields and filter fields for grids.
By their nature, Lists always have a list of items marked by a unique “key” parameter in the list, but which could be repeated in other lists.
Lists are a useful tool for creating custom fields as they allow you to create options for them without the need to write code, which makes it easy to create custom fields even for users less accustomed to programming.
