Installation

npx logic2b@latest add button-group

Working with an AI assistant? Copy this prompt into Claude Code, Cursor or Copilot — it carries the install steps, a no-CLI fallback and a verification checklist.

Add the "button-group" item from the logic2b ui registry (https://ui.logic2b.com) to this project. Follow every step and verify at the end.

## Steps

1. If the project has no `components.json` yet, set up logic2b ui first:

   ```bash
   npx logic2b@latest init
   ```

2. Install the item (the CLI resolves registry dependencies automatically):

   ```bash
   npx logic2b@latest add button-group
   ```

3. Install any npm dependencies the command prints.

## If the CLI is not available

Do it manually from the registry payload:

1. Fetch https://ui.logic2b.com/r/button-group.json.
2. Write every entry in `files[]` to its mapped project path (see below).
3. Repeat (recursively) for each name in `registryDependencies`.
4. Install every package listed in `dependencies` across those payloads.

## Registry reference

- Index of every item: https://ui.logic2b.com/r/index.json
- Item payload (full source): https://ui.logic2b.com/r/<name>.json
- Usage examples per item: https://ui.logic2b.com/r/demos/index.json → https://ui.logic2b.com/r/demos/<demo>.json
- Docs index for agents: https://ui.logic2b.com/llms.txt (full docs: https://ui.logic2b.com/llms-full.txt)
- Every docs page is Markdown when you append `.md` to its URL.

Registry file paths map to project paths like this:
- `ui/*` → `@/components/ui/*`
- `blocks/<name>/*` → `@/components/*`
- `charts/*` → `@/components/charts/*`
- `hooks/*` → `@/hooks/*`
- `lib/utils.ts` → `@/lib/utils.ts`
- `theme.css` → next to the project's Tailwind entry stylesheet

## Conventions (do not break these)

- Tailwind CSS v4 (CSS-first config; no tailwind.config.js needed) and React 19.
- All colors go through semantic tokens (`bg-primary`, `text-muted-foreground`,
  `border-border`, …). Never hardcode hex/oklch values in components.
- Dark mode is class-based: toggle `.dark` on `<html>`.
- Icons come from lucide-react.

## Verify before finishing

1. The dev server starts and the app renders without console errors.
2. TypeScript compiles (`tsc --noEmit` or the framework's check).
3. Components use the theme: a `<Button>` shows the primary token color,
   and toggling `.dark` on `<html>` switches the palette.

Copy into ui/button-group.tsx:

import * as React from "react"
import { Slot } from "radix-ui"

import { cn } from "@/lib/utils"
import { Separator } from "@/components/ui/separator"

function ButtonGroup({
  className,
  orientation = "horizontal",
  ...props
}: React.ComponentProps<"div"> & {
  orientation?: "horizontal" | "vertical"
}) {
  return (
    <div
      role="group"
      data-slot="button-group"
      data-orientation={orientation}
      className={cn(
        "flex w-fit items-stretch [&>*]:focus-visible:relative [&>*]:focus-visible:z-10 [&>input]:flex-1",
        orientation === "horizontal"
          ? "[&>*:not(:first-child)]:rounded-l-none [&>*:not(:first-child)]:border-l-0 [&>*:not(:last-child)]:rounded-r-none"
          : "flex-col [&>*:not(:first-child)]:rounded-t-none [&>*:not(:first-child)]:border-t-0 [&>*:not(:last-child)]:rounded-b-none",
        className
      )}
      {...props}
    />
  )
}

function ButtonGroupText({
  className,
  asChild = false,
  ...props
}: React.ComponentProps<"div"> & { asChild?: boolean }) {
  const Comp = asChild ? Slot.Root : "div"

  return (
    <Comp
      data-slot="button-group-text"
      className={cn(
        "bg-muted flex items-center gap-2 rounded-md border px-4 text-sm font-medium shadow-xs [&_svg:not([class*='size-'])]:size-4",
        className
      )}
      {...props}
    />
  )
}

function ButtonGroupSeparator({
  className,
  orientation = "vertical",
  ...props
}: React.ComponentProps<typeof Separator>) {
  return (
    <Separator
      data-slot="button-group-separator"
      orientation={orientation}
      className={cn(
        "bg-input relative !m-0 self-stretch data-[orientation=vertical]:h-auto",
        className
      )}
      {...props}
    />
  )
}

export { ButtonGroup, ButtonGroupText, ButtonGroupSeparator }

Usage

import { ButtonGroup, ButtonGroupSeparator, ButtonGroupText } from "@/components/ui/button-group"

<ButtonGroup>
  <Button variant="outline">Copy</Button>
  <Button variant="outline">Paste</Button>
</ButtonGroup>

<ButtonGroup>
  <ButtonGroupText>https://</ButtonGroupText>
  <ButtonGroupSeparator />
  <Button variant="outline">example.com</Button>
</ButtonGroup>

API

Prop	Type	Default
`orientation` (ButtonGroup)	`horizontal \| vertical`	`horizontal`
`orientation` (ButtonGroupSeparator)	`horizontal \| vertical`	`vertical`
`asChild` (ButtonGroupText)	`boolean`	`false`

All three parts also forward the native props of the element they render (ButtonGroup and ButtonGroupText render a <div>; ButtonGroupSeparator renders a Separator).

Examples

Vertical

import { MinusIcon, PlusIcon } from "lucide-react"

import { Button } from "@/components/ui/button"
import { ButtonGroup } from "@/components/ui/button-group"

export default function ButtonGroupVerticalDemo() {
  return (
    <ButtonGroup orientation="vertical">
      <Button variant="outline" size="icon" aria-label="Increment">
        <PlusIcon />
      </Button>
      <Button variant="outline" size="icon" aria-label="Decrement">
        <MinusIcon />
      </Button>
    </ButtonGroup>
  )
}

With an input

import { Button } from "@/components/ui/button"
import { ButtonGroup } from "@/components/ui/button-group"
import { Input } from "@/components/ui/input"

export default function ButtonGroupInputDemo() {
  return (
    <ButtonGroup className="w-[320px]">
      <Input placeholder="Search..." />
      <Button variant="outline">Search</Button>
    </ButtonGroup>
  )
}
