I have been searching so much through all those existing editors and just now stumbled upon ProseMirror. The initial blog post really points out all the problems contenteditable has and has strong ties to the post written by the medium guys (“why contenteditable is terrible”).
I have been talking with maintainers of other repositories on if it is possible to have multi-column / grid layouts (not tables!) inside a contenteditable. All of them told me: nope, very messy with contenteditable.
My question is if this is something that ProseMirror can solve as well or if it is out of this project’s scope. The most well-known grid system is by bootstrap: http://getbootstrap.com/css/#grid
The contenteditable inner would probably look something like:
<div contenteditable="true"> <div class="row"> <p class="col-xs-6">abcdef</p> <p class="col-xs-6">abcdef</p> </div> </div>
I hope my question is clear
