SelectableCard

A Card that is one selectable option; grouped into single (radio) or multiple (checkbox) sets via SelectableCardGroup.

Status: stable. Group: form. Markdown version: /design-system/components/selectable-card.md

When to use

Use SelectableCardGroup for visually prominent form choices, with SelectableCard children representing radio-style exclusive options or checkbox-style multiple options. The group owns the legend, value state, and error relationship.

When not to use

Do not nest interactive controls (buttons, links) inside a SelectableCard; the whole card is a label wrapping the input, so nested controls steal the click. Use a plain Card for action cards.
Do not use it for navigation; selecting must not commit or route on click.

Look-alikes

Card: Do not nest buttons or links inside a selectable card; use Card for action-oriented content.
CheckboxGroup: For bare text options without supporting content, use RadioGroup or CheckboxGroup.
RadioGroup: For bare text options without supporting content, use RadioGroup or CheckboxGroup.
