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。

Tab List

TabList provides tab-style navigation for organizing content into categorized sections. Use it to let users switch between related views without leaving the page, with overflow items handled by a built-in "more" menu.

使用建议

• Keep tab labels short and descriptive so users can quickly scan available sections.
• Leave overflow handling on: a strip narrower than its tabs scrolls, and the selected tab is kept in view. Use TabMenu when you want a curated group of extra options rather than a scrolling strip.
• When using hasDivider with action buttons alongside tabs, match the Button size to the TabList size (both md, both sm); the divided tab strip reserves space so tabs and same-size buttons align to a shared baseline above the rail.
• Reach for role="tablist" when the strip switches panels in place, and give each tab a panelId pointing at the panel it opens: that link is how a screen reader gets from a tab to its content. Leave it off for navigation between views.
• Set isFullBleed to stretch a tab bar inside a padded LayoutHeader, Card, or Section to the container's inline content edges, instead of reaching for negative-margin CSS.
• 避免：Use tabs for sequential steps or workflows; use a stepper or wizard pattern instead.
• 避免：Place more than 6–8 visible tabs before the overflow menu; prioritize the most important categories.
• 避免：Confuse TabList with SegmentedControl or ToggleButton. TabList is for navigation between views. SegmentedControl and ToggleButton are input controls: SegmentedControl always has exactly one selected option, while ToggleButton can be toggled on or off.
