An iframe element allows you to display a different web page in a framed box. In the context of the jumbo box, it is not allowed to embed iframe tags directly within the HTML before the user consents to cookies. This restriction ensures compliance with privacy regulations. To work around this limitation, instead of inserting an iframe, placeholder div must be used. Once the user accepts cookies, the script dynamically replaces the placeholder with the actual iframe. The placeholder div must contain all the necessary attributes (like src, width, height, etc.) that will be used in the final iframe. For implementations details, please refer to the example provided below.
