Measured entry

ruixen-faq-scroll-accordion

faqunclassifiedmotion on file

A shadcn registry client component for an FAQ that opens entries as they reach the center of its own scroll area. It uses React state, a container-scoped IntersectionObserver, Tailwind theme classes, CSS transitions, an inline SVG chevron, and the shadcn cn utility. It declares no package dependencies.

Verdict

A distinctive fit for short, curated FAQs where the internal scroll behavior is intentional. It mounts cleanly in the prepared harness, but the muted text needs contrast work. A bare project cannot mount it as shipped because it needs a shadcn-style setup, especially the aliased cn utility and theme classes.

Use it if

  • You want a compact FAQ whose active answer follows scrolling inside the component.
  • Your React app already has Tailwind theme tokens and a shadcn-compatible cn helper.
  • You want animation implemented with browser APIs and CSS rather than an animation package.

Skip it if

  • Your design cannot tolerate an internally scrolling FAQ with a hidden scrollbar.
  • You need the shipped colors to pass contrast checks without adjustment.
  • You require complete accordion disclosure attributes such as aria-expanded and aria-controls out of the box.
  • You prefer user-controlled expansion without scroll position automatically changing the open answer.

Providerno provider required in the harness

In a non-shadcn project, add Tailwind with the foreground, muted-foreground, and border theme classes used here, provide a cn class-merging helper, and either configure the at-sign source alias or replace that import with a local path. Keep it as a client component and ensure IntersectionObserver is available in supported browsers.
