Hi Confluence Team,
As we know the confluence Editor is feature rich and heavily engineered. Hence they should also provide support to use it in an iframe.
As there is a rest API available for editing a confluence page, but there are a lot of limitations such as attachments are not supported while adding through rest API, custom css are also not supported, and the many more.
Although it would have been great if we could have just provided page id and the page content would be directly available in a iframe, with all content and confluence rich features.
Let me know your thoughts upon this, as it would be quite easy for you to develop this feature, creating a great impact on the developer community.
Thanks,
