During March 2025, work focused on enhancing the FOSSBilling/FOSSBilling repository by delivering a multiselect payment gateway configuration feature within the Admin UI. This addition allowed administrators to select multiple payment gateways in a single configuration, improving flexibility and reducing setup time for merchants. The implementation involved updating macro_functions.html.twig to render the new multiselect element and maintain UI consistency throughout the interface. Utilizing skills in CSS, HTML, and front end development, the changes streamlined the gateway configuration process and minimized potential errors. No major bugs were reported during this period, reflecting a feature-driven approach with attention to user experience.
