            <h3>Icons</h3>
            <p>PrimeVue components internally use <a href="https://github.com/primefaces/primeicons" class="font-medium">PrimeIcons</a> library, the official icons suite from <a href="https://www.primetek.com.tr" class="font-medium">PrimeTek</a>.</p>

            <h5>Download</h5>
            <p>PrimeIcons is available at npm, run the following command to download it to your project.</p>

            <pre v-code><code>
npm install primeicons --save

</code></pre>

            <h5>Getting Started</h5>
            <p>PrimeIcons use the <strong>pi pi-&#123;icon&#125;</strong> syntax such as <strong>pi pi-check</strong>. A standalone icon can be displayed using an element like <i>i</i> or <i>span</i></p>

            <pre v-code><code>
&lt;i class="pi pi-check"&gt;&lt;/i&gt;
&lt;i class="pi pi-times"&gt;&lt;/i&gt;

</code></pre>

            <i class="pi pi-check" style="margin-right: 0.5rem"></i>
            <i class="pi pi-times"></i>

            <h5>Size</h5>
            <p>Size of the icons can easily be changed using font-size property.</p>

            <pre v-code><code>
&lt;i class="pi pi-check"&gt;&lt;/i&gt;

</code></pre>

            <i class="pi pi-check"></i>

            <pre v-code><code>
&lt;i class="pi pi-check" style="font-size: 2rem"&gt;&lt;/i&gt;

</code></pre>

            <i class="pi pi-check" style="font-size: 2rem"></i>

            <h5>Spinning Animation</h5>
            <p>Special pi-spin class applies continuous rotation to an icon.</p>
            <pre v-code><code>
&lt;i class="pi pi-spin pi-spinner" style="font-size: 2rem"&gt;&lt;/i&gt;

</code></pre>

            <i class="pi pi-spin pi-spinner" style="font-size: 2rem"></i>

            <h5>Constants</h5>
            <p>PrimeIcons constants API is provided to easily choose an icon with typescript e.g. when defining a menu model.</p>
            <pre v-code><code>
&lt;Menu :model="items" /&gt;

</code></pre>

            <pre v-code.script><code>
import {PrimeIcons} from 'primevue/api';

export default {
data() {
  return {
    items: [
      {
        label: 'Update',
