Selection
Chip group
Single or multiple selection, mandatory and max rules, and one tab stop — standalone chips still work.Choose it deliberately
Use the component when its contract matches the user task.
Use when
Several chips represent one choice or one multi-choice over a set of values.
Avoid overloading
It is not navigation, not a tab bar, and not a substitute for a select field with many options.
Composition
Sizing, labels, and neighboring elements should preserve visual hierarchy.
One primary meaning
Label the group and keep chip labels short and parallel in structure.
Overflow
Wrap by default; horizontal wrap=false scrolls natively without arrows or drag.
