Hello!
I have a composite form with a few panels on it. I'd like to see if I can make a panel be a URL:
I mocked up your scenario and in Chrome's Developer Tools console saw:
So your LPL syntax is correct and will work with any website that doesn't set an X-Frame-Options header, but won't with a security conscious website like Google.
For testing purposes I was able to successfully see the panel iframe work when I replace Google's URL with https://en.wikipedia.org.
If the website you want to place in the panel is under your company's control (or a partner's you can persuade to whitelist) there is an X-Frame-Options "ALLOW-FROM" response header that could whitelist your Landmark server's hostname.
Exactly. So when you use "url is ...." the website is hosted by Landmark in an iframe. Some websites will block themselves from being hosted in an iframe and some will not. Many do these days.
