During November 2024, Boilard extended the js_of_ocaml repository by adding support for the HTML details element, enabling OCaml applications to interact programmatically with this native browser feature. The work introduced new types for detailsElement and toggleEvent, allowing developers to build more accessible and interactive UIs directly in OCaml that run in the browser. By focusing on DOM manipulation and aligning OCaml bindings with HTML5 standards, Boilard laid the groundwork for richer component development in downstream web applications. The contribution demonstrated a focused, in-depth approach to enhancing browser-UI interoperability, though the scope was limited to a single feature without bug fixes.
