GroupLevelDef component

Obtained from the hierarchy palette, this component sets up a group to contain the results of one or more QueryLevelDefs that follow.

NOTE: At least one QueryLevelDef is required after a GroupLevelDef, at any subsequent position.

Property Value Description

Property	Value	Description
`Query Context`	Config Facets dialog box	The current location is one item that could be placed in the query context. The facet value is compared with the value of the context tag on a device or point at a lower level in the navigation tree. The query context can hold anything to be used in LevelDef queries. It is comparable to a hierarchy scoped variable. You could create multiple copies of such a hierarchy definition and then customize each copy with the query context of the specific hierarchy.
`Group By`	text string	Defines a single tag to use for grouping query results at the current level. For example, n:geoState groups all resulting data by the “n:geoState” tag on the Entity: AZ, CA, VA, etc.
`Sort`	None, Ascending (default), Descending	Determines the order in which results display.
