How to embed a iframe-thing?

I have a wiki site up and running and am thinking of transport it to Grav.

One of the sections I have is on Flutter development and I use

    {{url> 100%,600}}

in my current wiki to include an iframe so that the remote content can be displayed. It is working fine.

I am wondering if a similar plugin or any mechanism can help me to do the same?

Thanks for your help!

You can add plain HTML into the Markdown content:

<iframe id="iframe-responsive" src="/custom/apps/upload-manager/index.php" frameborder="no"></iframe>

Yes, it works! Thanks!
