XBRL dimensions can be viewed on the Concepts tab. You display the dimension view for an active taxonomy on the relationship view list (on the top right corner of the Concepts tab). After you select the dimension view, the top pane shows the primary items defined in the active taxonomy. The first item shows “Default Dimensions”. In the dimensions view, the “Dimension Members” pane is in the bottom pane of the Concepts tab.
When you select a primary item from the top pane, the Dimension Members pane (bottom pane) updates to display the dimension tree that represents the assignable domains and domain members related to the selected primary item.
When you select the default dimension item, the Dimension Members updates to display the default dimensions that are assignable to all taxonomy members.
