VisibleItemCountMode VisibleItemCountMode of the FacetFilter defines if the FacetFilter takes the whole available height (Auto) in the surrounding container, or is so high as needed to show 5 Items ("Fixed " - default). The FacetFilter always has as many items in the FacetFilterList as defined in the visibleItemCount property. The FacetFilter automatically fills the height of the surrounding container. The visibleItemCount property is automatically changed accordingly.
