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

</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/overlaypanel/overlaypanel.min.js"&gt;&lt;/script&gt;

</code></pre>

        <h5>Getting Started</h5>
        <p>OverlayPanel is accessed via its reference where visibility is controlled using toggle, show and hide methods.</p>
        <pre v-code><code>
&lt;Button type="button" label="Toggle" @click="toggle" /&gt;

&lt;OverlayPanel ref="op"&gt;
	&lt;img src="demo/images/nature/nature1.jpg" alt="Nature Image"&gt;
&lt;/OverlayPanel&gt;

</code></pre>

        <pre v-code.script><code>
toggle(event) {
    this.$refs.op.toggle(event);
}

</code></pre>

        <h5>Dismissable and CloseIcon</h5>
        <p>Clicking outside the overlay hides the panel, setting <i>dismissable</i> to false disables this behavior. Additionally enabling <i>showCloseIcon</i> property displays a close icon at the top right corner to close the panel.</p>
        <pre v-code><code>
&lt;OverlayPanel ref="op" :showCloseIcon="true" :dismissable="true"&gt;
	&lt;img src="demo/images/nature/nature1.jpg" alt="Nature Image"&gt;
&lt;/OverlayPanel&gt;

</code></pre>

        <h5>Responsive</h5>
        <p>
            OverlayPanel width can be adjusted per screen size with the <i>breakpoints</i> option. In example below, default width is set to 450px and below 961px, width would be 75vw and finally below 641px width becomes 100%. The value of
            <i>breakpoints</i> should be an object literal whose keys are the maximum screen sizes and values are the widths per screen.
        </p>

        <pre v-code><code>
&lt;OverlayPanel ref="op" :breakpoints="{'960px': '75vw', '640px': '100vw'}" :style="{width: '450px'}"&gt;
	Content
&lt;/OverlayPanel&gt;

        <h5>Accessibility</h5>
        <h6>Screen Reader</h6>
        <p>
            OverlayPanel component uses <i>dialog</i> role and since any attribute is passed to the root element you may define attributes like <i>aria-label</i> or <i>aria-labelledby</i> to describe the popup contents. In addition
            <i>aria-modal</i> is added since focus is kept within the popup.
        </p>
        <p>OverlayPanel adds <i>aria-expanded</i> state attribute and <i>aria-controls</i> to the trigger so that the relation between the trigger and the popup is defined.</p>

        <h6>OverlayPanel Keyboard Support</h6>
        <p>When the popup gets opened, the first focusable element receives the focus and this can be customized by adding <i>autofocus</i> to an element within the popup.</p>
