Sticky Section Bar
A horizontal section bar stuck to the top of a long page: the active item scrolls itself to the centre of the bar when it drifts off the edge.
React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.
What you can change
- the bar's screen-reader label through label
- the sections through sections: id, title and text
- the accent colour through accent
A link for your AI agent: preview, code and instructions.

FAQ
- How do I add Sticky Section Bar with Cursor or Claude Code?
- Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
- What does Sticky Section Bar depend on?
- No npm packages beyond React and Tailwind CSS.
- What can I change in Sticky Section Bar?
- Adapt: the bar's screen-reader label through label; the sections through sections: id, title and text; the accent colour through accent. Keep as installed: the local --vibeui-scrollspy-005-* palette — do not swap it for your theme tokens; sticky on the bar wrapper rather than the list: the list has no spare height and would scroll away at once; block:"nearest" in scrollIntoView — otherwise the whole page is pulled to centre.
- Is Sticky Section Bar free?
- Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

Technical notes
The component is self-contained: one file, no dependencies, the palette in local variables --vibeui-scrollspy-005-*. Client-side ("use client") — IntersectionObserver and scrollIntoView are needed. The bar sticks to the top of the reading area: sticky sits on the nav wrapper while the inner ul is what scrolls, because only an element whose parent has spare height can stick. The active item is brought to the centre by a scrollIntoView({block:"nearest",inline:"center"}) call — block:"nearest" is mandatory, otherwise the browser pulls the whole page to the centre. The highlight is an underline drawn with a pseudo-element plus aria-current.
