activeFloor
Type: string
Default: not set
Allows to render a multi-floor seating chart with specific floor selected, instead of the default all-floors view.
The possible values for this setting are the floor names, as they are displayed in the floor picker: "1", "2", etc.
If an unknown floor name is passed in, a warning is printed in the console, and the chart is rendered without any active floor (i.e. the default view).
