Month: 2025-08 — Focused on UI architecture improvements and stability fixes in Altinn/altinn-studio. Delivered an Accordion architecture refactor to the app-components pattern, migrated AccordionItem to app-components, and updated related layout components (Accordion, LayoutSetSummaryAccordion) to the new architecture. This work resolves a nested Details bug and enhances reusability across forms. Also stabilized UI by ensuring the progress bar renders only when currentPageId is available, preventing premature display during page transitions. Collectively, these changes improve UI reliability, developer productivity, and future feature scalability.
