<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;
&lt;script src="https://unpkg.com/primevue@^3/radiobutton/radiobutton.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>
