For a Tiki project, I need an intuitively-easy folding editor http://en.wikipedia.org/wiki/Folding_editor
or an Outliner that can allow folding.
CKEditor doesn't seem to have this capability.
The syntax editor allows for "hiding".
But what is needed must also include a numbering
system for sub entries. And needs GPL.
Suggestions as to what to look at would be appreciated.
