import { ChipGroup } from "@/forma/arc/chip-group/chip-group";

Base

In FORMA

Liegt in kit/arc/chip-group und ist über @/forma/arc/chip-group/chip-group erreichbar.
Farbe, Ecken, Höhen, Abstände, Tiefe, Schrift und Tempo kommen aus der Richtung (core/arc-bridge.ts); Arc behält Verhalten, Tastatur und Federn.

When to use

Facet filters people toggle often, like topics or categories.
Single clearable choices shown as chips, via multiple={false}.
Long option sets folded behind a +N more chip with maxVisible.

When not to use

Use multi-select when space is tight.
Use checkbox in forms.
Use segmented-control for one choice among a few views.

Usage

import { ChipGroup } from "@/forma/arc/chip-group/chip-group";

export function TopicFilter() {
  const [topics, setTopics] = useState<string[]>([]);
  return (
    <ChipGroup
      label="Topics"
      value={topics}
      onValueChange={setTopics}
      maxVisible={4}
      options={["Design", "Motion", "Code", "Research", "Writing"].map((t) => ({ value: t.toLowerCase(), label: t }))}
    />
  );
}

API reference

ChipGroup

Toggleable filter chips that morph when selected and fold long sets behind a +N more chip.

Prop	Type	Default	Description
`options` (required)	`{ value: string; label: string }[]`	–	Chips in order.
`value` (required)	`string[]`	–	Selected values.
`onValueChange` (required)	`(value: string[]) => void`	–	Called with the new selection, in option order.
`label` (required)	`string`	–	Accessible name of the group, such as "Topics".
`multiple`	`boolean`	`true`	Allow several chips. In single mode the selected chip can still be cleared.
`maxVisible`	`number`	`Infinity`	Chips shown before the rest fold. Selected chips always stay in view.
`className`	`string`	–	Added to the group.

Keyboard interactions

Keys	Action
Arrow keys	Move focus between chips and the more chip, wrapping.
Home / End	Focus the first or last chip.
Enter / Space	Toggles the focused chip or opens the overflow.

Accessibility

The group has role="group" and aria-label; each chip is a button with aria-pressed.
Roving tabindex keeps one chip in the tab order; the more chip uses aria-expanded.
Check icons and surfaces are aria-hidden.

Motion

Selecting grows a check in, slides the label over, and springs the chip edge while neighbours glide to new places, even across lines. Revealed chips stagger in and the group height morphs.
Reduced motion replaces the morphs with short fades.

Responsive behavior

Chips wrap onto new lines and the frame height follows on a spring.
Selected chips always stay visible, even beyond maxVisible, so folding never hides active filters.

Performance

Every chip has layout position animation and its own ResizeObserver; keep sets to a few dozen and fold the rest.
Revealed chips stagger in, capped at 0.3s total.

Notes for AI

Use for facet filters people toggle often. Use multi-select when space is tight and checkbox in forms.
Always controlled. Set multiple={false} for a single, clearable choice.
Exported as both named and default.

Also in selects

Select: A compact choice field with a keyboard friendly menu.
Combobox: Search and select from a list without leaving the field.
Morph select: A select whose trigger grows into the list, with a gliding highlight and type-ahead.

Guidance for AI tools

Chip group: Filter by a few facets with chips that morph as you pick them. Follow the declared prop types and do not invent props. Keep keyboard access, reduced motion support, and both light and dark themes intact when adapting it.
