Iframe within a panel

Hi, im using homeassistant for years now, waking up after my coma (2y ago) i could use some help to improve my frontend.

I was wondering if someone would perhaps now how i can put this iframe panel wihtin the skynettowerr section:
Currently:


Im finding a way to put the page into this test (on top) ad a section / card withing skynettower: It does kind off work: but its not full screen.

When i use that same yaml code ad page configration im getting a configuration error:



Here im unable to select something like a page or iframe

Does anyone know how to trick this to get it working?
Would be really nice as im narrowing done my panels

There has been some changes for iframe in the last year so : Webpage card - Home Assistant

found it!
just needed the panel view instead, sry! sharing the outcome so other might google this kind of info in future.


can a @moderators close it? TY

thank you, my best outcome was using a panel card instead
