GroupingLevel

Extended expression (used to describe a view level, for example).

Name	Description	Type
expression	Basic data.	Expression
show_folders_without_objects	True to show empty folders, false to hide them.	boolean
show_empty_value_folder	True to show the NULL folder, false to hide it.	boolean
show_objects_with_empty_value	True to show the contents of the NULL folder directly on this level.	boolean
property_folder_filter	The conditions that limit the values (property folders) of this expression.	SearchCondition[]
empty_value_folder_name	The name of the NULL folder. If NULL or an empty string, the default localized name is used.	string
show_only_user_selected_folders	True if the contents of this view level should be created on-demand only.	boolean
subfolder_algorithm	Folder listing algorithm used to determine matching property folders on this intermediate view level.	FolderListingAlgorithm
options_obsolete	Bit flags that provide additional information on the extended expression.	number
options	Bit flags that provide additional information on the extended expression.	EXPRESSIONEXFLAGS
expression_object_type	The ID of the object type to group-by in this view level.	number
reference_direction	True if the result objects are referred from this view level.	boolean
