I am experimenting with using an embed to display a URL in an iFrame. So for example, each collection template page would display whatever URL is entered into the CMS.
I must be doing something wrong and I can’t get it to work! Any pointers appreciated.
The other sites are blocking you from framing their sites. As I would. Webflow would probably not.
I tried also with webflow links and it still does not work. In fact, what I was trying to build was a webflow repository of components that would point to individual webflow project links.
