Usage

Basic disclosure group

DisclosureGroup is most commonly used inside a Form so it picks up the standard iOS list styling with a chevron indicator.

BasicDisclosureGroupExample.tsx

import { useState } from 'react';
import { DisclosureGroup, Form, Host, Section, Text } from '@expo/ui/swift-ui';

export default function BasicDisclosureGroupExample() {
  const [isExpanded, setIsExpanded] = useState(true);
  return (
    <Host style={{ flex: 1 }}>
      <Form>
        <Section>
          <DisclosureGroup
            label="Advanced settings"
            isExpanded={isExpanded}
            onIsExpandedChange={setIsExpanded}>
            <Text>Auto-update apps</Text>
            <Text>App downloads</Text>
            <Text>Offload unused apps</Text>
          </DisclosureGroup>
        </Section>
      </Form>
    </Host>
  );
}

Initially expanded

Set isExpanded to true initially to show the content by default.

InitiallyExpandedExample.tsx

import { useState } from 'react';
import { Host, DisclosureGroup, Text } from '@expo/ui/swift-ui';

export default function InitiallyExpandedExample() {
  const [isExpanded, setIsExpanded] = useState(true);

  return (
    <Host matchContents>
      <DisclosureGroup label="Details" isExpanded={isExpanded} onIsExpandedChange={setIsExpanded}>
        <Text>This content is visible by default.</Text>
      </DisclosureGroup>
    </Host>
  );
}

Custom label

Use DisclosureGroup.Label when the label needs custom SwiftUI content or modifiers instead of the label string prop.

CustomLabelDisclosureGroupExample.tsx

import { useState } from 'react';
import { DisclosureGroup, Form, Host, Section, Text } from '@expo/ui/swift-ui';
import { font, foregroundStyle } from '@expo/ui/swift-ui/modifiers';

export default function CustomLabelDisclosureGroupExample() {
  const [isExpanded, setIsExpanded] = useState(false);

  return (
    <Host style={{ flex: 1 }}>
      <Form>
        <Section>
          <DisclosureGroup isExpanded={isExpanded} onIsExpandedChange={setIsExpanded}>
            <DisclosureGroup.Label>
              <Text modifiers={[font({ weight: 'semibold' }), foregroundStyle('#0a7ea4')]}>
                Network options
              </Text>
            </DisclosureGroup.Label>
            <Text>Wi-Fi</Text>
            <Text>Bluetooth</Text>
            <Text>Cellular data</Text>
          </DisclosureGroup>
        </Section>
      </Form>
    </Host>
  );
}
