Complex UI components like custom selects are hard to build accessibly, but component frameworks (React, Vue, Web Components) can help by encapsulating accessibility internals — semantics, keyboard behavior, focus management, and ARIA attributes — so that only one team needs to solve these problems correctly, and everyone else can reuse the result without worrying about the details. The post walks through building a custom select using radio buttons and a toggle button with aria-expanded and aria-controls, then argues that wrapping this in a declarative component abstraction ensures consistent, accessible behavior across a codebase. The author also acknowledges the downside: framework complexity can gatekeep front-end accessibility work from specialists who lack advanced JavaScript skills.
