Adjusting Section size to iframe widget

[maciekkielbus]

Hi.
While configuring my dashboard i hit a hard spot.
I try to set one section to be my local camera preview.
Everything works fine , but there is a major problem.
I cannot to adjust section size to my iframe window, its like collapsed the whole time and I cant get it open just to show the whole image of iframe source.
On the image below you have a preview of my case.

I dont want to use scrolls, instead i want to see the whole image without section being collapsed.
Is there any way to do this?
Thanks in advance for answers. :)

Hi that is what I use, this works fine for me:

    widgets:
      - type: embed
        options:
          html: >
            <p align="center"><iframe
            src="{url}"
            frameborder='0' scrolling="no" style=" width: 540px; height: 615px;
            overflow: hidden;"></iframe></p>

this also centers the iframe in the section and removes scroll bar.
