Recipe: Button group + split-button design
A reusable pattern for grouping related actions with an optional dropdown split.
Basic button group
Inline-flex container with zero-radius inner borders and outer rounding.
Split button
Primary action with a secondary dropdown trigger sharing a border.
Icon-only group
Compact toolbar variant with square buttons.
Tip: Use overflow-hidden on the parent to clip inner borders. Split buttons work best when the primary action is the most common path.
