Lars Selstad enhanced the TableRowExpandable component in the SpareBank1/designsystem repository, focusing on improving flexibility for front-end developers. He implemented a dynamic expandContent feature in ffe-tables-react, allowing expandContent to be provided as a function with access to setIsOpen, which enables programmatic control over expanded table rows. To illustrate this new capability, Lars added an ExpandableAndClosable story featuring a Close button, improving developer guidance and usability. His work utilized React, TypeScript, and JavaScript, demonstrating solid component development and UI/UX skills. Over the month, Lars delivered one well-scoped feature, contributing depth and maintainability to the codebase.
