Usage

import {
  Attachment,
  AttachmentAction,
  AttachmentActions,
  AttachmentContent,
  AttachmentDescription,
  AttachmentMedia,
  AttachmentTitle,
} from "@/components/ui/attachment"

<Attachment>
  <AttachmentMedia>
    <FileTextIcon />
  </AttachmentMedia>
  <AttachmentContent>
    <AttachmentTitle>sales-dashboard.pdf</AttachmentTitle>
    <AttachmentDescription>PDF · 2.4 MB</AttachmentDescription>
  </AttachmentContent>
  <AttachmentActions>
    <AttachmentAction aria-label="Remove sales-dashboard.pdf">
      <XIcon />
    </AttachmentAction>
  </AttachmentActions>
</Attachment>

Composition

Use the following composition to build an attachment:

Attachment
├── AttachmentMedia
├── AttachmentContent
│   ├── AttachmentTitle
│   └── AttachmentDescription
├── AttachmentActions
│   └── AttachmentAction
└── AttachmentTrigger

Use AttachmentGroup to lay out multiple attachments in a scrollable row:

AttachmentGroup
├── Attachment
└── Attachment

Features

Icon and image media through AttachmentMedia
Upload states: idle, uploading, processing, error, and done with built-in styling and a shimmer while in progress
Three sizes and horizontal or vertical orientation
A full-card AttachmentTrigger that opens a link or dialog while the actions stay independently clickable
Scrollable, snapping AttachmentGroup with an edge fade
Customizable styling through the className prop on every part

Image

Set variant="image" on AttachmentMedia and render an <img> inside it. Use orientation="vertical" to stack the media above the content.

Trigger

Add an AttachmentTrigger to make the whole card open a link or dialog. It fills the card behind the actions, so the actions stay clickable.

</Dialog>

Accessibility

AttachmentAction renders a Button, and AttachmentTrigger renders a real <button> (or your element via render). Follow the guidance below so both are operable and announced.

Label icon-only actions

AttachmentAction is usually icon-only, so give each one an aria-label describing the action and its target.

<AttachmentAction aria-label="Remove sales-dashboard.pdf">
  <XIcon />
</AttachmentAction>

Label the trigger

AttachmentTrigger covers the card with no text of its own, so give it an aria-label for what activating it does.

<AttachmentTrigger
  render={
    <a
      href={url}
      target="_blank"
      rel="noreferrer"
      aria-label="Open workspace.png"
    />
  }
/>

The trigger sits behind the actions in the stacking order, so an AttachmentAction and the AttachmentTrigger never trap each other — both remain separately focusable and clickable.

Keyboard scrolling

An AttachmentGroup scrolls horizontally. When its attachments are interactive: a trigger or actions, keyboard users reach off-screen items by tabbing to them. For a row of presentational attachments, make the group itself focusable and scrollable by adding tabIndex={0}, role="group", and an aria-label.

Meaning beyond color

The error state uses a destructive color. Keep the failure reason in AttachmentDescription so the state is not conveyed by color alone.

Notes

render is supported on the server (element or function), like Base UI.
Accepts class instead of className.
Upstream documentation: shadcn/ui Attachment. See also Differences from shadcn/ui.
