Badge Overflow

BadgeOverflow displays as many custom badges as fit within a configurable number of flex-wrapped lines, replacing remaining items with an overflow badge such as “+3”. It measures badge widths and the container with ResizeObserver, and supports primitive or object item arrays.

Installation

pnpm dlx shadcn@latest add https://diceui.com/r/radix-vega/badge-overflow.json

Usage

usage.tsx
import { BadgeOverflow } from "@/components/ui/badge-overflow";<BadgeOverflow  items={["Design", "Engineering", "Product"]}  renderBadge={(item) => <span className="rounded-md border px-2 py-0.5 text-xs">{item}</span>}/>
  • Use when a compact collection of tags, filters, participants, statuses, or categories must fit within a constrained width.
  • Use when the number of visible badges should adapt automatically to the container width.
  • Use when overflow should be represented by a custom control, label, or action such as “+4 more”.
  • Use with object arrays when badge labels need to be derived from a property such as name or title.

Examples

Object items with a label selector

Use getBadgeLabel when items are objects and render each item with its own badge content.

object-items-with-a-label-selector.tsx
import { BadgeOverflow } from "@/components/ui/badge-overflow";const labels = [  { id: "1", name: "Design" },  { id: "2", name: "Engineering" },  { id: "3", name: "Research" },];<BadgeOverflow  items={labels}  getBadgeLabel={(item) => item.name}  renderBadge={(item, label) => (    <span key={item.id} className="rounded-md bg-muted px-2 py-0.5 text-xs">      {label}    </span>  )}/>

Two-line status badges

Allow badges to wrap across two lines and provide a custom overflow label.

two-line-status-badges.tsx
import { BadgeOverflow } from "@/components/ui/badge-overflow";<BadgeOverflow  items={["Queued", "Running", "Needs review", "Blocked", "Complete"]}  lineCount={2}  renderBadge={(item) => (    <span className="rounded-md border px-2 py-0.5 text-xs">{item}</span>  )}  renderOverflow={(count) => (    <span className="rounded-md bg-secondary px-2 py-0.5 text-xs">      +{count} more    </span>  )}/>

Custom numeric overflow action

Render primitive values as compact badges and turn the overflow indicator into a button-like element.

custom-numeric-overflow-action.tsx
import { BadgeOverflow } from "@/components/ui/badge-overflow";<BadgeOverflow  items={["React", "TypeScript", "Tailwind CSS", "Radix UI"]}  className="max-w-sm"  renderBadge={(item) => (    <span className="rounded-full bg-blue-100 px-2 py-1 text-xs text-blue-700">      {item}    </span>  )}  renderOverflow={(count) => (    <span className="rounded-full border px-2 py-1 text-xs">View +{count}</span>  )}/>

API reference

PropTypeDefaultDescription
itemsT[]requiredThe items to render and measure.
getBadgeLabel(item: T) => stringoptional for primitive arrays; required for object arraysReturns the string label used to identify and measure each item. The component throws an error at runtime when an object item array is used without this callback.
lineCountnumber1Maximum number of flex-wrapped lines considered when deciding which items are visible.
renderBadge(item: T, label: string) => React.ReactNoderequiredRenders each badge. It receives the original item and the resolved label.
renderOverflow(count: number) => React.ReactNodeundefinedRenders the overflow badge when items are hidden. If omitted, the component renders a default bordered badge containing +{count}.
asChildbooleanundefinedWhen true, uses Radix Slot instead of a div for the root element, allowing root props and attributes to be merged onto a child element.
refReact.Ref<HTMLDivElement>undefinedA forwarded ref composed with the component's internal measurement ref.
classNamestringundefinedInherited div class name. The component also applies flex flex-wrap.
styleReact.CSSPropertiesundefinedInherited div styles. Component-managed gap is applied first and user styles are spread afterward, so a supplied gap can override the measured gap.
...rootPropsReact.ComponentProps<"div">undefinedAll other standard div props, including data attributes, event handlers, id, role, and aria attributes.

Accessibility

  • The component does not add a semantic role, accessible name, or ARIA attributes by itself; add them through standard div props when the badge collection needs semantics.
  • Ensure renderBadge produces meaningful text or accessible content for each badge.
  • If renderOverflow is interactive, render an actual button or another keyboard-accessible control and provide an accessible name.
  • The invisible measurement container is implementation detail and should not be relied on for accessible content.
  • When using asChild, ensure the slotted element remains an appropriate semantic and keyboard-accessible element for its purpose.
  • The component depends on client-side layout measurement and initially renders a placeholder layout before measurement completes.
