If you have an web site that you want to present to members, you can use an iframe widget to present its entry page. The widget presents the page to members as a web page in the Space's working area, which they can interact with as if they had accessed it directly. This could be used to give members of a company's Space access to the company's website from within the Space.
Type the URL of the page that you want to include into the URL field.
Note: The target page is included in the Spaces page, and to display it properly, Spaces must have been granted permission to do so by the target page (using an Access-Control-Allow-Origin header). Since many HTML sites are unlikely to do this, an iframe widget is most useful when you also control the cross-origin resource sharing of the web site that you want to include.
