Expanding Stack

A stack that spreads open to show everyone: the expansion hangs on hover and on focus alike, because a keyboard has no hover.

# Install and place "avatar-031" (Expanding Stack) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/avatar-031.json

Registry item: https://vibeui.ru/r/avatar-031.json
Installs to: components/vibeui/avatar-031.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A stack that spreads open to show everyone: the expansion hangs on hover and on focus alike, because a keyboard has no hover.

An overlapping avatar row that spreads open on hover and on keyboard focus. Every face is its own button. Zero dependencies, one file, no client JS.

## 3. How to use it
import { Avatar031 } from "@/components/vibeui/avatar-031"

<Avatar031
  names={["Anna Rebrova", "Ilya Mokhov", "Kim Son"]}
  overlap={55}
  size="md"
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-avatar-031-* palette — do not swap it for your theme tokens
- expanding on both :hover and :focus-within — hover does not exist on a keyboard
- the overlap via negative margin rather than absolute positioning: otherwise the row's width lies
- the button around every face: in a dense stack a circle is half-covered and cannot be clicked
- the reversed z-index: without it the stack reads right to left
- the prefers-reduced-motion rule that removes the transition

## 6. You may change
- the names array
- the stack density through overlap — a percentage of the size
- the face size through size — sm, md or lg
- the circle ring colour for your surface

## 7. Rules
- An expanded stack is wider and pushes its neighbours: put it last in a row or budget the space.
- Layering is written for five positions: add nth-child rules for a longer row.
- Only the first five names show: trim the tail in the caller and offer a "show all" link.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/avatar-031.json
https://vibeui.ru/r/avatar-031.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-avatar-031-*. Серверный: хуков нет, раскрытие целиком на CSS. Перекрытие задано отрицательным margin в долях размера, поэтому одно число управляет и плотностью, и шириной строки, а раскрытие — это тот же margin, уезжающий в ноль с переходом. Раскрытие висит на :hover и на :focus-within: на клавиатуре наведения нет. Каждое лицо — отдельная кнопка с доступной подписью: закрытый наполовину кружок нажать нельзя.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Avatar031Props = Omit<
  ComponentPropsWithoutRef<"ul">,
  "children"
> & {
  names?: string[]
  overlap?: number
  size?: "sm" | "md" | "lg"
}

// Идея компонента: стопка, которая раздвигается и показывает всех. Плотная
// стопка экономит место, но лица в ней наполовину закрыты и по ним не нажать;
// раздвигать её по наведению мало — на клавиатуре наведения нет, поэтому
// раскрытие висит и на :focus-within. Перекрытие задано отрицательным margin в
// долях размера, поэтому одно число управляет и плотностью, и шириной строки, а
// раскрытие — это просто margin, уезжающий в ноль.
