Not necessary, the plugin does work with wikis and documents as it turns out.
Unfortunately, it’s not what I call drag and drop, the process could use a bit of simplification. May I suggest? providing content areas that can be dragged to the text field, then fitted out with the desired functions. Header function, image function, text function, that sort of thing.
For a look at something like that sort of thing search for the keyword “lucidpress”. It’s an online page layout app that comes close to what I’m talking about.
In any case, my thanks for your assistance.
