API 与上游详细参考

优先使用 0.7.1 官方中文说明；上游尚未提供中文的条目保留英文。属性名、类型及默认值保持原生 API，不把示例状态名称当成组件属性。

Selectable Card

A card that toggles between selected and unselected states with an accent border. For navigation use ClickableCard.

属性	类型	默认值	说明
label *	string		Accessibility label.
isSelected *	boolean		Controlled selection state.
onChange *	(isSelected: boolean) => void		Called when toggled.
isDisabled	boolean	false	Disables the card.
children	ReactNode		Card content.
padding	0 \| 0.5 \| 1 \| 1.5 \| 2 \| 3 \| 4 \| 5 \| 6 \| 8 \| 10	4	Inner padding.
variant	'default' \| 'transparent' \| 'muted' \| 'blue' \| 'cyan' \| 'gray' \| 'green' \| 'orange' \| 'pink' \| 'purple' \| 'red' \| 'teal' \| 'yellow'	'default'	Background color variant.
elevation	'none' \| 'low' \| 'med' \| 'high'	'none'	Resting shadow depth. The selection ring composes on top, so a selected card keeps its shadow.
width	SizeValue		Card width.
height	SizeValue		Card height.
maxWidth	SizeValue		Maximum card width.
xstyle	StyleXStyles		StyleX styles for layout customization (margins, positioning, sizing). Must be a stylex.create() value, not an inline style object like style={{}}.

使用建议

Use for plan pickers, filter chips, or option grids.
For single-select track one ID; for multi-select use a Set.
When focused, toggle selection with Space or Enter.
避免：Use for navigation; use ClickableCard for that.
