During December 2025, Adrien Lepoutre focused on front end development within the strapi/strapi repository, addressing a persistent issue with sub-navigation height overflow in the Strapi admin interface. By leveraging React and applying dynamic layout techniques in JavaScript and TypeScript, Adrien implemented a solution that calculates navigation height based on content scrollHeight, ensuring that long lists remain fully visible and accessible. This fix improved the user experience by preventing menu truncation and reducing navigation friction for administrators. The work demonstrated careful debugging and collaborative problem-solving, contributing to the overall stability and usability of the Strapi admin panel during the period.
