In the great post by Peter Sunna (http://world.episerver.com/Articles/Items/EPiServer-75-CMS--starting-to-show-its-full-potential/) there is a new EPiServer 7.5 feature that we would like to use:
It’s been a long time coming, but blocks can now finally be dragged not only into content areas, but also into rich-text areas. This makes it easier to create, for example, a video with floating text around it without having to create several blocks.
However we would like to limit the CMS editors to a subset of all the system blocks. Is there a way to limit the types of block that can be dragged into a rich text area?
