# mapView.insets.borderPath

A geometry object of type `MultiLineString` defining the border path of the inset in terms of `units`. If undefined, a border is rendered around the `field` geometry. It is recommended that the `borderPath` partly follows the outline of the `field` in order to make pointer positioning consistent.
