Auto Width

Key Properties

autoWidth: number

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

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