## What is this?

The main purpose of this library is adding classnames for accessing Radix data attributes, which gains you the benefit of auto-completion compared to using `data-*` variants.

**TL;DR** It's [@headlessui-tailwindcss](https://github.com/tailwindlabs/headlessui/tree/main/packages/@headlessui-tailwindcss) for Radix.

## Installation

```sh
# For v3 compatibility
pnpm add tailwindcss-radix@3
# For v4 compatibility
pnpm add tailwindcss-radix
```

## Demo

## Usage

### With [@plugin directive](https://tailwindcss.com/docs/functions-and-directives#plugin-directive) (recommended)

**Default prefix**
```css
/* Generates `radix-[state/side/orientation]-*` utilities for `data-[state/side/orientation]="*"` */
@plugin "tailwindcss-radix";
```

**Custom prefix**
```css
/* Generates `rdx-[state/side/orientation]-*` utilities for `data-[state/side/orientation]="*"` */
@plugin "tailwindcss-radix" {
  variantPrefix: rdx;
}
```

### With [@config directive](https://tailwindcss.com/docs/functions-and-directives#config-directive)

**Default prefix**
```js
module.exports = {
  // --snip --
  plugins: [
    // Generates `radix-[state/side/orientation]-*` utilities for `data-[state/side/orientation]="*"`
    require("tailwindcss-radix")(),
  ],
};
```

**Custom prefix**
```js
module.exports = {
  // --snip --
  plugins: [
    // Generates `rdx-[state/side/orientation]-*` utilities for `data-[state/side/orientation]="*"`
    require("tailwindcss-radix")({
      variantPrefix: "rdx",
    }),
  ],
};
```

**Load configuration**
```css
@config "../../tailwind.config.js";
```

### Styling state

#### Basic usage

This plugin works with CSS attribute selectors. Use the variants based on the `data-*` attribute added by Radix.

```tsx
import React from "react";
import * as DropdownMenuPrimitive from "@radix-ui/react-dropdown-menu";

const App = () => {
  return (
    <DropdownMenuPrimitive.Root>
      <DropdownMenuPrimitive.Trigger className="border-black radix-state-open:border-2">
        Trigger
      </DropdownMenuPrimitive.Trigger>
      <DropdownMenuPrimitive.Content>
        <DropdownMenuPrimitive.Item>Item</DropdownMenuPrimitive.Item>
      </DropdownMenuPrimitive.Content>
    </DropdownMenuPrimitive.Root>
  );
};

export default App;
```

#### Accessing parent state

When you need to style an element based on the state of a parent element, mark the parent with the `group` class and style the target with `group-radix-*` modifiers.

Example usage of a conditional transform for a Radix `Accordion`:

```tsx
import React from "react";
import * as AccordionPrimitive from "@radix-ui/react-accordion";
import { ChevronDownIcon } from "@radix-ui/react-icons";

const Accordion = () => {
  return (
    <AccordionPrimitive.Root type="multiple">
      <AccordionPrimitive.Item value="item-1">
        <AccordionPrimitive.Header>
          <AccordionPrimitive.Trigger className="group">
            <div className="flex items-center">
              Item 1
              <ChevronDownIcon className="w-5 h-5 ml-2 transform group-radix-state-open:rotate-180" />
            </div>
          </AccordionPrimitive.Trigger>
        </AccordionPrimitive.Header>
        <AccordionPrimitive.Content>Content 1</AccordionPrimitive.Content>
      </AccordionPrimitive.Item>
      <AccordionPrimitive.Item value="item-2">
        <AccordionPrimitive.Header>
          <AccordionPrimitive.Trigger className="group">
            <div className="flex items-center">
              Item 2
              <ChevronDownIcon className="w-5 h-5 ml-2 transform group-radix-state-open:rotate-180" />
            </div>
          </AccordionPrimitive.Trigger>
        </AccordionPrimitive.Header>
        <AccordionPrimitive.Content>Content 2</AccordionPrimitive.Content>
      </AccordionPrimitive.Item>
    </AccordionPrimitive.Root>
  );
};

export default App;
```

#### Accessing sibling state

When you need to style an element based on the state of a sibling element, mark the sibling with the `peer` class and style the target with `peer-radix-*` modifiers.

Example usage of a conditional icon color for a sibling of a Radix `Checkbox`:

```tsx
import * as CheckboxPrimitive from "@radix-ui/react-checkbox";
import { CheckIcon, TargetIcon } from "@radix-ui/react-icons";
import React from "react";

interface Props {}

const App = (props: Props) => {
  return (
    <>
      <CheckboxPrimitive.Root id="c1" defaultChecked className="peer h-5 w-5">
        <CheckboxPrimitive.Indicator>
          <CheckIcon />
        </CheckboxPrimitive.Indicator>
      </CheckboxPrimitive.Root>

      <TargetIcon className="text-red-500 peer-radix-state-checked:text-green-500" />
    </>
  );
};

export default App;
```

#### Disabled state

Use the generated `disabled` variant.

```tsx
import React from "react";
import * as ContextMenuPrimitive from "@radix-ui/react-context-menu";

const ContextMenu = () => {
  return (
    // --snip--
    <ContextMenuPrimitive.Item
      disabled
      className="radix-disabled:opacity-50 radix-disabled:cursor-not-allowed"
    >
      Item
    </ContextMenuPrimitive.Item>
    // --snip--
  );
};
```

### CSS Variable Utilities

## Migrate from v1

To prevent a possible future name clashing the `skipAttributeNames` option has been removed. In case you used this option, please update the class names accordingly.

## Migrate from v2

In case you use `content-available` utilities:

- Add `-content-available` to the width-based classnames
- Remove `width` and `height` from `content-available-[width|height]`
