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

Features

Auto-Variant Assignment: Automatically assigns Primary/Tertiary/Secondary variants based on button count (override with forceVariant)
Responsive Layout: Vertical stack on mobile, horizontal row on tablet+ (for 1-2 buttons)
Block Layout: 3+ buttons render as all tertiary in a vertical block layout
Customizable Spacing: Control gap between buttons on tablet+ (none or small)
Theme Support: Green or black color themes
Max Buttons Limit: Optionally limit the number of buttons rendered

Button Behavior

The component automatically determines button variants based on count:

Count	Behavior
1 button	Renders as Primary (or Secondary with `singleButtonVariant="secondary"`)
2 buttons	First as Primary, second as Tertiary (responsive layout)
3+ buttons	All as Tertiary in block layout (vertical on all screen sizes)

Overriding the variant

Pass forceVariant when a section's design calls for one uniform treatment no matter how many buttons it receives. It supersedes both the count-based defaults and singleButtonVariant; layout (inline vs. block) still follows the count.

When forcing tertiary at 1-2 buttons, pair it with forceNoPadding so the labels sit flush with the surrounding text instead of being indented by the button's horizontal padding. (The 3+ block layout is always flush, so it sets this for you.)

<ButtonGroup
  buttons={[{ label: 'Learn More', href: '/learn' }]}
  forceVariant="tertiary"
  forceNoPadding
/>

FeatureTwoColumn is the reference consumer of this.

Usage

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

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

// Single button as Secondary
<ButtonGroup
  buttons={[
    { label: "Learn More", href: "/learn" }
  ]}
  singleButtonVariant="secondary"
  color="green"
/>

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

// Three or more buttons (auto: all Tertiary, block layout)
<ButtonGroup
  buttons={[
    { label: "Documentation", href: "/docs" },
    { label: "API Reference", href: "/api" },
    { label: "Tutorials", href: "/tutorials" }
  ]}
  color="black"
/>

// 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}
  color="green"
/>
