Toggle — logic2b/ui

import { ItalicIcon } from "lucide-react"

import { Toggle } from "@/components/ui/toggle"

export default function ToggleDemo() {
  return (
    <Toggle aria-label="Toggle italic">
      <ItalicIcon />
    </Toggle>
  )
}

Installation

npx logic2b@latest add toggle

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 "toggle" 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 toggle
   ```

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/toggle.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.

Install the dependencies:

npm install radix-ui class-variance-authority

Copy into ui/toggle.tsx:

import * as React from "react"
import { Toggle as TogglePrimitive } from "radix-ui"
import { cva, type VariantProps } from "class-variance-authority"

import { cn } from "@/lib/utils"

const toggleVariants = cva(

      variant: "default",
      size: "default",
    },
  }
)

function Toggle({
  className,
  variant,
  size,
  ...props
}: React.ComponentProps<typeof TogglePrimitive.Root> &
  VariantProps<typeof toggleVariants>) {
  return (
    <TogglePrimitive.Root
      data-slot="toggle"
      className={cn(toggleVariants({ variant, size, className }))}
      {...props}
    />
  )
}

export { Toggle, toggleVariants }

Usage

import { Toggle } from "@/components/ui/toggle"

<Toggle aria-label="Toggle italic">
  <ItalicIcon />
</Toggle>

API

Built on Radix Toggle.Root with cva variants.

Prop	Type	Default
`variant`	`default \| outline`	`default`
`size`	`default \| sm \| lg`	`default`
`pressed`	`boolean` — controlled state	—
`defaultPressed`	`boolean`	—
`onPressedChange`	`(pressed: boolean) => void`	—
`disabled`	`boolean`	`false`

Examples

Outline

import { ItalicIcon } from "lucide-react"

import { Toggle } from "@/components/ui/toggle"

export default function ToggleOutlineDemo() {
  return (
    <Toggle variant="outline" aria-label="Toggle italic">
      <ItalicIcon />
    </Toggle>
  )
}

With text

import { BoldIcon } from "lucide-react"

import { Toggle } from "@/components/ui/toggle"

export default function ToggleTextDemo() {
  return (
    <Toggle aria-label="Toggle bold" className="px-3">
      <BoldIcon />
      Bold
    </Toggle>
  )
}

Sizes

import { StarIcon } from "lucide-react"

import { Toggle } from "@/components/ui/toggle"

export default function ToggleSizesDemo() {
  return (
    <div className="flex items-center gap-2">
      <Toggle size="sm" variant="outline" aria-label="Favorite, small">
        <StarIcon />
      </Toggle>
      <Toggle size="default" variant="outline" aria-label="Favorite, default">
        <StarIcon />
      </Toggle>
      <Toggle size="lg" variant="outline" aria-label="Favorite, large">
        <StarIcon />
      </Toggle>
    </div>
  )
}

Accessibility

Exposes aria-pressed so its on/off state is announced.
Toggle with Space or Enter when focused; reachable with Tab.
Icon-only toggles need an aria-label to provide an accessible name.
