Auto Height

Key Properties

autoHeight: number

Auto height weight. Distributes remaining height to this element (ignores height), similar to Flex grow / shrink. Default is 0.

When set to a value greater than 0, the element will automatically expand its height. Usually set to 1. Percentage-based height support will be added in the future.
