Expandable Features Blocks for Shadcn UI

When each capability has real depth, a flat grid won’t do it justice. Expandable features—tabs, accordions, and progressive disclosure—let you show summaries up front and reveal detail on demand.

When to use expandable features

Some features can’t be summarized in a card. Expandable patterns let you ship the full story without flattening the rest of the page into walls of text.

• A feature deserves a screenshot, list, or short paragraph
• The page already has a hero and a grid—you want depth without scroll fatigue
• Different audiences care about different features (tabs help self-segment)

Patterns

Tabs, accordions, and steppers are different tools for the same problem. The right one depends on whether users will compare panels or read them in order.

1. Vertical tabs with sticky media on the right
2. Horizontal tab row with a single live preview region
3. Accordion list with inline media inside each panel
4. Stepper-style disclosure that walks through a flow

Accessibility

Tabbed interfaces have a long list of right answers and an even longer list of broken implementations. Use the primitives shadcn ships and you’ll get most of the way there for free.

• Use Tabs with proper roles (tablist, tab, tabpanel) or shadcn’s primitive
• Make tabs keyboard navigable: Left/Right between tabs, Home/End to jump
• Announce panel changes with aria-live="polite" only when content is dynamic
• Respect prefers-reduced-motion and skip slide/fade animations when set

Motion

Disclosure animations should feel like the panel is responding to you, not performing for you. Keep them short, keep them linear, and keep them optional for users who prefer reduced motion.

• Crossfade panels at 120–180ms; longer transitions feel sluggish on click
• Animate height with interpolate-size or measured height to avoid jumps
• Avoid stacked animations (slide + fade + scale)—one feels intentional, three feels noisy

Copy and content

Inside an expandable panel, every sentence has the user’s full attention. Don’t waste it warming up—open with the answer to "what is this and why does it matter?"

• Keep tab labels under 3 words; titles inside panels can be longer
• Order panels by audience priority, not feature scope
• Each panel should answer "what is this and why does it matter?" in the first sentence
