Examples

Variants

Use variant to change the visual treatment of the bubble.

A bubble sizes to its content, up to 80% of the container width. The ghost variant removes the max-width so assistant text and rich content can span the full row.

Alignment

Use align on Bubble to align the bubble to the start or end of the conversation.

Note: When building chat interfaces, you probably want to use alignment on the Message component itself, not the Bubble component. You can use the role prop on the Message component to automatically align the bubble to the start or end of the conversation.

Bubble Group

Use BubbleGroup to group consecutive bubbles from the same sender. Note the align prop should be set on the Bubble component itself, not the BubbleGroup component.

Links and Buttons

You can turn a bubble into a link or button by using the asChild prop on BubbleContent.

import { Bubble, BubbleContent } from "@/components/ui/bubble"

export function BubbleLinkDemo() {
  return (
    <Bubble variant="muted">
      <BubbleContent asChild>
        <button>Click here</button>
      </BubbleContent>
    </Bubble>
  )
}

Reactions

Use BubbleReactions for bubble reactions. You can use it to display reactions or quick action buttons. Use side and align to position the row — side="top" anchors it to the upper edge. Reactions overlap the bubble edge, so leave vertical space between rows — the examples below use a larger gap for this reason.

Show More / Collapsible

Long bubble content can be composed with Collapsible to allow for a show more or show less interaction. Use the CollapsibleTrigger component to trigger the collapsible content.

Tooltip

Wrap a bubble in a Tooltip to reveal metadata on hover, such as when a message was read.

Popover

Pair a bubble with a Popover to surface more information on demand, such as the full error message for a failed action.

Accessibility

Bubble renders the presentational message surface. Keep conversation-level semantics on the surrounding container and follow the guidelines below.

Labeling Reactions

Reactions render as a row of emoji. A screen reader reads each glyph with no context, and counters like +8 are announced as "plus eight". Group the row as a single image with a descriptive aria-label so it announces once. role="img" also hides the individual emoji from assistive tech, so no aria-hidden is needed.

<BubbleReactions role="img" aria-label="Reactions: thumbs up, fire, and 8 more">
  <span>👍</span>
  <span>🔥</span>
  <span>+8</span>
</BubbleReactions>

When reactions are interactive, render buttons instead and give icon-only buttons an aria-label.

<BubbleReactions>
  <Button aria-label="Thumbs up" variant="secondary" size="icon-xs">
    <ThumbsUpIcon />
  </Button>
</BubbleReactions>

Interactive Bubbles

When a bubble is clickable, render it as a real <button> or <a> with the asChild prop so it is focusable and exposes the correct role. BubbleContent ships a visible focus ring for interactive elements, and the accessible name comes from the bubble text. No extra label is needed.

<Bubble variant="muted" align="end">
  <BubbleContent asChild>
    <button type="button" onClick={onReply}>
      I forgot my password
    </button>
  </BubbleContent>
</Bubble>

Meaning Beyond Color

Bubble variants signal role and tone with color. Pair them with text, alignment, or icons so meaning is not conveyed by color alone. For a destructive bubble, keep the error context in the message text rather than relying on the color treatment.
