The Labels widget (formerly called the Facets widget) can be configured to display all contributing labels in the project or a combination of desired labels.
Hovering over the label field displays the distribution of actual label values, sorted by the top 10 values.
Clicking on an individual value filters the result list. Multi-selection of values is supported as well by pressing the modifier key,
Cmd for Apple Macs,
Ctrl for Microsoft Windows systems.
Tip: The widget can be displayed as a list or as dropdown buttons.
