You can specify the density of information displayed in the filter. By default, the filter's information density is displayed in Comfortable mode, which provides more space between fields in the filter pane. You can specify the information display density to be more compact.
Before you begin: Select a single root object whose structure you want to filter, then open the filter pane. For more information, see User Interface: Filter Commands.
If you want a tighter display of the information in a smaller area, from the filter's context menu, select Compact.
If you want a looser display of the information in a larger area, from the filter's context menu, select Comfortable.
