Installation

pnpm dlx shadcn@latest add @kibo-ui/avatar-stack

Requires @kibo-ui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { AvatarStack } from "@/components/kibo-ui/avatar-stack";export function Example() {  return (    <AvatarStack size={40} animate>      <div data-slot="avatar" className="flex items-center justify-center bg-blue-500 text-sm text-white">AB</div>      <div data-slot="avatar" className="flex items-center justify-center bg-emerald-500 text-sm text-white">CD</div>      <div data-slot="avatar" className="flex items-center justify-center bg-orange-500 text-sm text-white">EF</div>    </AvatarStack>  );}
  • Use for showing a group of users, contributors, teammates, or participants in a compact space.
  • Use when the full group should remain visually recognizable while minimizing horizontal layout space.
  • Enable animate when users benefit from seeing individual items separate on hover.
  • Use the size prop when the stack needs to match a specific avatar scale.

Examples

Static participant stack

A compact, non-animated stack for showing several participants.

static-participant-stack.tsx
import { AvatarStack } from "@/components/kibo-ui/avatar-stack";export function ParticipantStack() {  return (    <AvatarStack size={36}>      <div data-slot="avatar" className="flex items-center justify-center bg-sky-600 text-xs font-medium text-white">JD</div>      <div data-slot="avatar" className="flex items-center justify-center bg-violet-600 text-xs font-medium text-white">MK</div>      <div data-slot="avatar" className="flex items-center justify-center bg-pink-600 text-xs font-medium text-white">RS</div>    </AvatarStack>  );}

Animated team stack

A larger stack that expands its spacing when hovered.

animated-team-stack.tsx
import { AvatarStack } from "@/components/kibo-ui/avatar-stack";export function TeamStack() {  return (    <AvatarStack animate size={48} className="ring-1 ring-border">      <div data-slot="avatar" className="flex items-center justify-center bg-blue-700 font-semibold text-white">AL</div>      <div data-slot="avatar" className="flex items-center justify-center bg-green-700 font-semibold text-white">BM</div>      <div data-slot="avatar" className="flex items-center justify-center bg-amber-600 font-semibold text-white">CN</div>    </AvatarStack>  );}

Avatar components as children

The stack can wrap existing avatar components or any React nodes.

avatar-components-as-children.tsx
import { AvatarStack } from "@/components/kibo-ui/avatar-stack";import { Avatar, AvatarFallback, AvatarImage } from "@/components/ui/avatar";export function UserStack() {  return (    <AvatarStack size={40}>      <Avatar>        <AvatarImage src="/avatars/olivia.png" alt="Olivia Martin" />        <AvatarFallback>OM</AvatarFallback>      </Avatar>      <Avatar>        <AvatarImage src="/avatars/liam.png" alt="Liam Chen" />        <AvatarFallback>LC</AvatarFallback>      </Avatar>    </AvatarStack>  );}

API reference

PropTypeDefaultDescription
childrenReactNode—The React content rendered as stacked items. Each non-null child is wrapped in a circular, clipped container.
classNamestring | undefined—Optional class names applied to the outer stack container and also to each generated child wrapper.
animateboolean | undefinedfalseWhen true, adds hover spacing expansion and transition classes: the stack changes from overlapping spacing to zero spacing on hover, and child wrappers transition.
sizenumber | undefined40The width and height, in pixels, applied to every generated child wrapper. It also controls the radial overlap mask geometry.

Accessibility

  • The component renders a plain div and does not add an ARIA role or label; provide surrounding context when the group needs a name.
  • Preserve accessible names on avatar children, such as meaningful alt text on images or accessible fallback text.
  • Use empty alt text for purely decorative avatar images so they are ignored by assistive technology.
  • The hover animation is visual-only and has no built-in reduced-motion handling; consider applying an external reduced-motion strategy if needed.
