Default

The <Radio /> component serves as a container for <Radio.Option /> sub-components, each representing a distinct option. To assign a label to an option, include it within <Radio.Option />. By default, no option is preselected.

"use client";

import { Radio } from "@heathmont/moon-core-tw";
import { useState } from "react";

const Default = () => {
  const [value, setValue] = useState("");
  return (
    <Radio value={value} onChange={setValue}>
      <Radio.Option value="option1">
        <Radio.Indicator />
      </Radio.Option>
      <Radio.Option value="option2">
        <Radio.Indicator />
      </Radio.Option>
    </Radio>
  );
};

export default Default;

Uncontrolled

      Option 1
    </Radio.Option>
    <Radio.Option value="option2">
      <Radio.Indicator />
      Option 2

          Option 3
        </Radio.Option>
      </Radio>
    </>
  );
};

export default Disabled;

As form item

To integrate the <Radio /> component as a form item, add the name property. Data transfer occurs through a hidden <input /> tag.

Option 1

Option 2

"use client";

import { Radio } from "@heathmont/moon-core-tw";
import { useState } from "react";

const AsFormItem = () => {
  const [value, setValue] = useState("");

    <Radio value={value} onChange={setValue} name="Form Item">
      <Radio.Option value="option1">
        <Radio.Indicator />
        Option 1
      </Radio.Option>
      <Radio.Option value="option2">
        <Radio.Indicator />
        Option 2
      </Radio.Option>
    </Radio>
  );
};

export default AsFormItem;
