Contributed to the ant-design/ant-design repository by developing dynamic page size options for the Pagination component, allowing the selector to adjust based on the total item count. This feature was implemented in both the Pagination component and the global ConfigProvider, enhancing configurability and consistency across the UI. The work included adding support for the pagination.totalBoundaryShowSizeChanger setting, which helps reduce clutter in page size selectors for large datasets. Documentation was updated in Markdown to reflect these changes, ensuring clear guidance for users. The implementation leveraged React and TypeScript, focusing on front end development and maintainable, scalable component configuration.
