Carolina Mallo enhanced the Select component in the SUI-Components repository by introducing a searchable user interface with improved layering and positioning. She implemented a dedicated container for the search input and dropdown, addressing z-index and visual stability issues that previously caused dropdown overlap and glitches. Using React, JavaScript, and SCSS, Carolina refined the component structure to align with the design system and support maintainability and future extensibility. Her work improved the end-user experience in forms requiring searchable selects, reducing interaction friction and ensuring consistent behavior across usage contexts. The update focused on usability and robust front-end development practices.
