export type toolboxLocationType = "left" | "right" | "sidebar";

To hide the toolbox, it is necessary to set the creator.toolboxLocation property to "none". However, toolboxLocationType doesn't actually include the "none" option.

Thanks, @OlgaLarina, for the recommendation to use the creator.showToolbox option. However, it is not currently listed in SurveyCreatorModel API.
We should add it.
