FBML Essentials

Name

<fb:iframe/>

Synopsis

<fb:iframe src="..."/>

An excellent tool when you need to render complex JavaScript, Flash, or unsupported FBML. This tag links to an external web address and renders the content from that URL inside an HTML <iframe/> tag on the canvas page. From the external URL, any HTML, JavaScript, or Flash may be used, but keep in mind that content will not be parsed by Facebook, and therefore FBML will not be supported for anything output by the <fb:iframe/> tags. <fb:iframe/> is not supported on user profile pages.
