Usage

import {
  Accordion,
  AccordionContent,
  AccordionIndicator,
  AccordionItem,
  AccordionTrigger,
} from "@/components/ui/accordion";
import { ShoppingCartIcon } from "@/components/ui/icons";
import { Stack } from "@/components/ui/stack";
import { Text } from "@/components/ui/text";

<Accordion type="single" collapsible defaultValue="shipping">
  <AccordionItem value="shipping">
    <AccordionTrigger>
      <Stack className="flex-1 items-center" direction="row" gap="sm">
        <ShoppingCartIcon className="size-5 text-muted-foreground" />
        <Text className="flex-1 font-medium">Shipping information</Text>
      </Stack>
      <AccordionIndicator />
    </AccordionTrigger>
    <AccordionContent>
      <Text className="text-muted-foreground">
        Orders ship within 2–3 business days.
      </Text>
    </AccordionContent>
  </AccordionItem>
  <AccordionItem value="returns">
    <AccordionTrigger>
      <Text className="flex-1 font-medium">Return policy</Text>
      <AccordionIndicator />
    </AccordionTrigger>
    <AccordionContent>
      <Text className="text-muted-foreground">
        Returns are accepted within 30 days of delivery.
      </Text>
    </AccordionContent>
  </AccordionItem>
</Accordion>

Single vs multiple

Use type="single" (default) to allow one open section at a time, or type="multiple" to allow several sections open at once:

<Accordion type="multiple" defaultValue={["notifications", "privacy"]}>
  {/* ... */}
</Accordion>

Collapsible

When type is single, set collapsible to allow closing the active item so none remain open:

<Accordion type="single" collapsible>
  {/* ... */}
</Accordion>

Controlled

Pass value and onValueChange for controlled state:

const [value, setValue] = useState<string | undefined>("shipping");

<Accordion
  type="single"
  collapsible
  value={value}
  onValueChange={setValue}
>
  {/* ... */}
</Accordion>

Custom trigger

Use asChild on AccordionTrigger to compose with other pressable components:

<AccordionTrigger asChild>
  <Button variant="ghost" className="w-full justify-between">
    <ButtonText>Custom trigger</ButtonText>
    <AccordionIndicator />
  </Button>
</AccordionTrigger>

Closed items that sit next to each other are visually grouped with no gap between them. When an item opens, it separates from its neighbors with vertical spacing so the expanded content reads as its own card.
