true if the navbar's specific elements can be hot-tracked; otherwise, false.
Some elements of the NavBar extension's user interface can respond to mouse movement i.e. change their appearance, when the mouse pointer is being moved over them. These elements are items and headers of groups in particular. Note that items can be hot-tracked if they belong to a group whose NavBarGroup.ItemLinkMode property is set to the GroupItemLinkMode.ContentBounds value (or to the GroupItemLinkMode.Default value if the navbar's NavBarSettings.ItemLinkMode property is set to GroupItemLinkMode.ContentBounds).
Use the EnableHotTrack property to control the availability of the hot-tracked state for the specific elements (items and headers) when the mouse pointer hovers over them. The style used to represent the hot-tracked state is specified via the AppearanceStyle.HoverStyle property which can be available via the corresponding style settings of an element.
