        <h5>Import via Module</h5>
        <pre v-code.script><code>
import RadioButton from 'primevue/radiobutton';

</code></pre>

        <h5>Import via CDN</h5>
        <pre v-code><code>
&lt;script src="https://unpkg.com/primevue@^3/core/core.min.js"&gt;&lt;/script&gt;

</code></pre>

        <h5>Getting Started</h5>
        <p>Two-way value binding is defined using the standard v-model directive.</p>
        <pre v-code><code>
&lt;RadioButton name="city" value="Chicago" v-model="city" /&gt;
&lt;RadioButton name="city" value="Los Angeles" v-model="city" /&gt;

</code></pre>
        <pre v-code.script><code>
export default {
	data() {
		return {
			city: null
		}
	}
}

</code></pre>
        <p>As model is two-way binding enabled, giving a default value to the model is enough to display a radio button as checked by default.</p>
        <pre v-code.script><code>
export default {
	data() {
		return {
			city: 'Chicago'
		}
	}
}

</code></pre>

        <h5>Properties</h5>
        <p>Any valid attribute is passed to the root element implicitly, extended properties are as follows;</p>

        <p>
            RadioButton component uses a hidden native radio button element internally that is only visible to screen readers. Value to describe the component can either be provided via <i>label</i> tag combined with <i>id</i> prop or using
            <i>aria-labelledby</i>, <i>aria-label</i> props.
        </p>

        <pre v-code><code>
&lt;label for="rb1"&gt;One&lt;/label&gt;
&lt;RadioButton inputId="rb1" /&gt;

&lt;span id="rb2"&gt;Two&lt;/span&gt;
&lt;RadioButton aria-labelledby="rb2" /&gt;

&lt;RadioButton aria-label="Three" /&gt;
