Usage

import { HoverCard, HoverCardTrigger, HoverCardContent } from "@/components/ui/hover-card"<HoverCard>  <HoverCardTrigger>Hover or focus me</HoverCardTrigger>  <HoverCardContent>A short preview appears here.</HoverCardContent></HoverCard>
  • Show a brief preview of a profile, link, or item without navigating away.
  • Reveal supplementary information when a user hovers over or focuses a trigger.
  • Use when the preview is helpful but not essential to the main task.

Examples

Profile preview

Show a short profile summary from a name trigger.

profile-preview.tsx
import { HoverCard, HoverCardTrigger, HoverCardContent } from "@/components/ui/hover-card"<HoverCard>  <HoverCardTrigger>@maya</HoverCardTrigger>  <HoverCardContent>Maya is a designer based in Kyoto.</HoverCardContent></HoverCard>

Link preview

Offer context for a link without replacing the link’s navigation behavior.

link-preview.tsx
import { HoverCard, HoverCardTrigger, HoverCardContent } from "@/components/ui/hover-card"<HoverCard>  <HoverCardTrigger>Design system guide</HoverCardTrigger>  <HoverCardContent>A practical guide to reusable interface patterns.</HoverCardContent></HoverCard>

API reference

PropTypeDefaultDescription
HoverCardPreviewCardPrimitive.Root.Props—Props are forwarded to Base UI’s PreviewCard Root, including the primitive’s supported state and behavior props.
HoverCardTriggerPreviewCardPrimitive.Trigger.Props—Props are forwarded to Base UI’s PreviewCard Trigger.
HoverCardContentPreviewCardPrimitive.Popup.Props & Pick<PreviewCardPrimitive.Positioner.Props, "align" | "alignOffset" | "side" | "sideOffset">—Popup props are forwarded to the Popup, and align, alignOffset, side, and sideOffset configure the Positioner. Defaults: side="bottom", sideOffset=4, align="center", alignOffset=4. className is merged with the component’s base styles.

Accessibility

  • Use descriptive trigger text so the preview has a meaningful entry point for assistive technology.
  • Keep essential information and actions available outside the hover preview; users should not need hover to complete a task.
  • The trigger and popup use Base UI primitives. Preserve their default interaction behavior when adding custom markup or styling.
