I done a partial page (usercontrol) which makes it possible to drag n drog a page from the page tree and into a contentarea where it renders like any other block.
I want to be able to have the same functionality for the xhtml field. It seems like default episerver behavior is to render the page as a link () inside the xhtml field.
Is it possible to get some pages to render like blocks inside xhtml field?
You will have to create a UIDescriptor for your pages/base page. I have an example on how to do this in my blog: http://world.episerver.com/blogs/Linus-Ekstrom/Dates/2013/12/Customizing-the-look-and-behavior-in-the-UI-for-your-content-types/
