Thank you for writing in to the Axure Forums! Axure RP does not currently have an Autolayout feature similar to Figma’s. This is something that we are looking into for a future release of Axure RP, and I have added your feedback to this Feature Request with our Product Team.
We greatly appreciate all feedback on the product, and you can write in directly to support@axure.com with any other Feature Requests or questions that you may have. Thank you!
