I have some static pages into which I want to allow users to drop a partial with a pre-formatted card layout. Existing cards are all held within a container div to preserve formatting.

If I try to insert a snippet in the wysiwyg editor, I cannot get it to to reside within the container, It just creates a new div elsewhere which breaks the layout. I can do it by manually accessing the code mirror but obviously I don't want users to have to do this. Does anybody have any ideas how to overcome this
