Activates one-click selection mode.
If you pass in
numberOfPlacesToSelect: 3, the ticket buyer only needs to click once to select 3 places. Previously selected places are deselected automatically.
The ticket buyer is not allowed to leave orphan seats, unless it's not possible to select seats in that row without leaving orphans. At that point, a warning is triggered if you activated the
noOrphanSeats selection validator.
numberOfPlacesToSelect works for seats (both row and table seats) and general admission areas. It has no effect when selecting booths or entirely selectable tables.
