Accordion

Collapsible panel with an animated header and content area. Expand/collapse state is controlled by the parent.

Basic Usage

import { Accordion, Typography } from '@multinaire/expo-ui';
import { useState } from 'react';

function Example() {
  const [active, setActive] = useState(false);

  return (
    <Accordion
      active={active}
      title="Section title"
      onPress={() => setActive(!active)}
    >
      <Typography>Panel content</Typography>
    </Accordion>
  );
}

Props

Prop	Type	Default	Description
active	boolean	false	When true, the panel content is expanded
leading	IconName	—	Icon name rendered before the title
title	TranslationKey	—	Header title
badge	ReactElement	—	Badge element rendered after the title, before the trailing icon
trailing	IconName	dropdown chevron	Icon name for the trailing indicator. Defaults to a chevron (ArrowUp2/ArrowDown2) reflecting active
onPress	() => void	—	Press handler for the header. When omitted, the header renders at reduced opacity to indicate it is non-interactive

Examples

With Leading Icon

<Accordion
  active={active}
  leading="InfoCircle"
  title="More information"
  onPress={() => setActive(!active)}
>
  <Typography color="neutral">Additional details go here.</Typography>
</Accordion>

With Badge

<Accordion
  active={active}
  title="Notifications"
  badge={<Badge type="primary" title="3" />}
  onPress={() => setActive(!active)}
>
  <Typography>You have 3 unread notifications.</Typography>
</Accordion>

Custom Trailing Icon

<Accordion
  active={active}
  title="Settings"
  trailing="ArrowRight2"
  onPress={() => setActive(!active)}
>
  <Typography>Panel content</Typography>
</Accordion>

Non-Interactive Header

<Accordion active title="Read-only section">
  <Typography>This panel has no press handler, so the header renders dimmed.</Typography>
</Accordion>

Accordion Group

function AccordionGroup() {
  const [openIndex, setOpenIndex] = useState<number | null>(0);

  return (
    <Container gap={variables.gap.medium}>
      {sections.map((section, index) => (
        <Accordion
          key={section.title}
          active={openIndex === index}
          title={section.title}
          onPress={() =>
            setOpenIndex(openIndex === index ? null : index)
          }
        >
          <Typography>{section.content}</Typography>
        </Accordion>
      ))}
    </Container>
  );
}

Notes

• Accordion is a controlled component — the parent owns active state and toggles it via onPress.
• The panel is built on Card, so it inherits the theme's border, radius, and background.
• Expand/collapse is animated with react-native-reanimated by measuring the content's height and animating to it, so surrounding layout doesn't jump.
• The content is re-measured whenever it changes size, so children that load or grow after mount are handled automatically — an open panel animates to its new height, and a closed one opens to the correct height next time. A panel rendered with active already true starts open rather than animating open on mount.
