Input Group

A bordered shell that joins an input or textarea with addons, buttons and text, sharing one focus ring.

Stock shadcn base-nova. Clicking an addon focuses the control, unless the click lands on a button. The chat composer is the one real use: a quote strip in a block-start addon, the InputGroupTextarea, and send and stop buttons in a block-end addon.

The group is h-8, which doesn't agree with InputGroupInput: it inherits Input's h-11 below md, so a single-line group will overflow on touch screens until one of them gives. I've only used it with a textarea so far, where the group goes h-auto. Icons also follow a different convention here: InputGroupButton sizes bare svg children rather than data-icon ones.

import {
  InputGroup,
  InputGroupAddon,
  InputGroupButton,
  InputGroupTextarea,
} from "@/components/ui/input-group";
 
<InputGroup>
  <InputGroupTextarea aria-label="Message" rows={1} />
  <InputGroupAddon align="block-end">
    <InputGroupButton aria-label="Send" className="ml-auto" size="icon-xs" type="submit">
      <ArrowUpIcon />
    </InputGroupButton>
  </InputGroupAddon>
</InputGroup>

Props

Prop	Type	Default
InputGroupAddon align	inline-start \| inline-end \| block-start \| block-end	inline-start
InputGroupButton size	xs \| sm \| icon-xs \| icon-sm	xs
InputGroupButton variant	Button variant	ghost
InputGroupButton type	button \| submit \| reset	button

Rules

The same rules ship in DESIGN.md and the MCP server, for the agents building with this.

must
Put InputGroupInput or InputGroupTextarea inside the group, never a bare Input or Textarea.
The shared focus and invalid rings watch for data-slot="input-group-control", which only the group's own controls set.
use-group-controls
must
Use InputGroupButton for buttons inside an InputGroupAddon, and pass type="submit" explicitly for a send button, since it defaults to type="button".
buttons-in-addons
must
Give every icon-only InputGroupButton (size="icon-xs" or size="icon-sm") an aria-label.
icon-buttons-named
should
Use align="block-start" or align="block-end" on InputGroupAddon for rows above or below a textarea, and the inline-* values for prefixes and suffixes on a single-line input.
