Popover

A click-triggered overlay anchored to a button or trigger element. Use it for secondary actions, inline confirmations, or supplementary information that does not warrant a full dialog. For hover previews use HoverCard, for brief helper text use Tooltip.

使用建议

• Keep popover content focused on a single task or piece of information.
• Provide a clear way to close: either by clicking outside or with an explicit close button.
• Theme the painted surface through the canonical popover target.
• 避免：Nest popovers inside other popovers; it creates confusing focus and navigation.
• 避免：Assume input complexity alone determines the presentation; evaluate the task's focus, space, and interaction requirements.
• 避免：Assume scrolling alone means Popover is the wrong component; a bounded Popover may scroll while a focused anchored interaction remains appropriate.

Flush surface for a list of rows

<Popover
  label="Recent files"
  padding={0}
  content={
    <List>
      <ListItem label="Quarterly report.pdf" />
      <ListItem label="Roadmap.key" />
    </List>
  }>
  <Button label="Recent" variant="secondary" />
</Popover>

Roomier surface for a form

<Popover
  label="Save search"
  padding={4}
  content={<SaveSearchForm />}>
  <Button label="Save search" variant="secondary" />
</Popover>

Popover

一个点击触发的弹出框，用于显示锚定到触发元素的交互式内容。

组件结构

• Trigger element: Caller-supplied or externally referenced control that anchors and toggles the popover.
• Popover surface: Painted surface owned and themed by Popover through the canonical popover target.
• Popover content: Caller-supplied content rendered inside the surface.
• Fallback close control: Keyboard-reachable close affordance appended by usePopover when enabled.

usePopover

Headless hook for click-triggered popovers with focus trapping. Combines useLayer with useFocusTrap, auto-focus, light dismiss, Escape handling, and an optional hidden close button for accessible dialog-like popover behavior. Every painted surface emits the canonical popover target. A custom composition needing a distinct stable seam should pass and document its own surfaceTarget.

]

使用建议

• Use for interactive content such as menus, pickers, forms, and command panels that need focus management.
• Prefer the Popover component for standard trigger-content pairs; use the hook for custom trigger patterns.
• Use popover as the broad canonical surface target.
• When a custom composition needs its own theme refinement, pass and document an owned surfaceTarget such as selector-popup. It refines the Popover surface rather than creating another anatomy part.
• 避免：Use for non-interactive hover previews: use useHoverCard or useTooltip instead.

示例的 StyleX 编译要求

PopoverBottomSheetAlternative 包含 stylex.create，需要配置 StyleX 源码编译流程。仅引入 Core 预编译 CSS 不足以运行这些示例样式，复制前请阅读样式与 Tailwind。
