Can I insert an iframe in my web page?

Xara Web Designer / Designer Pro allow you to insert any HTML via the Placeholder tab accessed via the Website Properties dialog. This means you can insert an iframe into your webpage created in Xara. Information on creating an iframe and its attributes can be viewed at w3schools.com  

Current versions of Web Designer and Designer Pro include a widget in Elements under Print & Web Components > Other Components called 'Embed a website'. This widget provides a quick means of displaying an external website within an iframe.
