ButtonGroup Component

A responsive button group container that assigns button emphasis based on the number of buttons passed. Stacks vertically on mobile and horizontally on tablet+.

• Auto Emphasis: Assigns emphasis by button count (override with forceEmphasis)
• Responsive Layout: Vertical stack on mobile, horizontal row on tablet+ (for 1-2 buttons)
• Block Layout: 3+ buttons render as a vertical block
• Customizable Spacing: Control gap between buttons on tablet+
• Surface Support: One surface selects the token group for the whole set
• Max Buttons Limit: Optionally limit the number of buttons rendered

The component determines emphasis by count:

Pass forceEmphasis for one uniform treatment no matter how many buttons the section receives. It supersedes both the count-based defaults and singleButtonEmphasis; layout (inline vs. block) still follows the count.

An all-subtle set renders as Links rather than Buttons, so the labels sit flush with the surrounding text. FeatureTwoColumn is the reference consumer.

<ButtonGroup
  buttons={[{ label: 'Learn More', href: '/learn' }]}
  forceEmphasis="subtle"
/>

import { ButtonGroup } from 'shared/patterns/ButtonGroup';

// Single button (strong by default)
<ButtonGroup buttons={[{ label: "Get Started", href: "/start" }]} />

// Single button as standard
<ButtonGroup
  buttons={[{ label: "Learn More", href: "/learn" }]}
  singleButtonEmphasis="standard"
/>

// Two buttons (auto: strong + subtle)
<ButtonGroup
  buttons={[
    { label: "Get Started", href: "/start" },
    { label: "Learn More", href: "/learn" }
  ]}
/>

// Three or more (auto: all subtle, block layout) on a solid brand block
<ButtonGroup
  buttons={[
    { label: "Documentation", href: "/docs" },
    { label: "API Reference", href: "/api" },
    { label: "Tutorials", href: "/tutorials" }
  ]}
  surface={{ context: "on-saturated" }}
/>

// Limit to 2 buttons even if more are passed
<ButtonGroup
  buttons={[
    { label: "First", href: "/first" },
    { label: "Second", href: "/second" },
    { label: "Third (not rendered)", href: "/third" }
  ]}
  maxButtons={2}
/>
