Focus Format

A form-field instruction tooltip that opens specifically on keyboard focus: clicking the select with a mouse never shows it, tabbing to it always does.

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 field caption through label and the instruction through hint
  • the value options through options
  • the field name through name

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Focus Format 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 Focus Format depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Focus Format?
Adapt: the field caption through label and the instruction through hint; the value options through options; the field name through name. Keep as installed: the local --vibeui-tooltip-016-* palette — do not swap it for your theme tokens; the :focus-visible selector instead of :focus or :focus-within — that is what separates keyboard from mouse; the general sibling selector (~) between select and hint — both must be DOM siblings with no wrapper between them.
Is Focus Format free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

npx shadcn@latest add https://vibeui.club/r/pro/tooltip-016.json

This command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options

Technical notes

The component is self-contained: one file, no dependencies, its own palette in local variables --vibeui-tooltip-016-*. It is a server component: the hint is bound to :focus-visible of the select itself through the general sibling selector (~) rather than to :focus-within of the wrapper. The browser marks focus on a select as "visible" only when it was reached by keyboard — a mouse click sets no such mark, so the hint opens exclusively while tabbing. For a text field this technique will not work: on text inputs focus is always "visible".
