parameterGroups property

Map of parameter group names to their descriptions and grouped parameters.

A group's name is mutable but must be unique among groups in the config. The name is limited to 256 characters and intended to be human-readable. Any Unicode characters are allowed. Groups have a list of parameters which allows users of the API to group parameters that are associated with the same feature or theme together for easy organizational access. For example, a parameter group with the name "Search V2" may have the description "New mobile search view" and contain parameters for the new search's layout and font.
