Options include: `Required` (always visible, default); `OptionalAndHidesLowerPriority` (visible only if no overlap, higher `zIndex` prevails); and `RequiredAndHidesOptional` (always visible, hides `OptionalAndHidesLowerPriority`). `zIndex` determines priority in overlapping markers, with lower vertical screen position breaking ties in specific cases. Setting `collisionBehavior` in code allows customization of display logic. It's recommended to use the same behavior for all advanced markers.\n"]]
