Answered Which rich text editor to use?

Fred is not a rich text editor though, it's a visual content builder (like ContentBlocks) that optionally supports RTEs for some content elements.

There's ample choice for RTEs these days. The "TinyMCE" package is rather old, and while it still works, it's not going to get updated to newer versions of TinyMCE. "TinyMCE RTE" is a more recent version that is nicely integrated. TinyMCEWrapper is a bit more work to set up last I checked, but would be the most up-to-date version of tinymce.js and gives you more flexibility to configure it as if it's a standalone editor integration. CKEditor is also available, but has some issues playing ball with third party extras that load RTEs. There's also "TinyMCE for Fred", which is, as the name suggests, only meant to be used with Fred. And there's Redactor, the only premium RTE, which comes with support and a huge v3 release this summer. Check the reviews to see what users think.

There is no single "best" option between all of those, so I'd suggest to try them and pick your favorite

Thanks Mark, I didn't realize that FRED didn't have a built-in RTE.

I should mention that NewsPublisher allows front-end rich-text editing for Resources and TVs, (but not chunks or templates). It loads TinyMCE 4 directly via CDN and uses the El Finder image/file browser. It's nice if you want to let users edit Resources and TVs without having to enter the Manager. You can also create new Resources with it. It also lets you put an "Edit" button on front-end resources for logged-in users that launches NewsPublisher to edit that page (with or without RTE).

Redactor is a great choice for RTE work, and according to user reviews, is well worth the price. I would use it, but I do all my work in raw HTML.

For a free RTE in the Manager, I would use TinyMceWrapper. It takes a little work to set up, but is highly configurable.

Fred has a built-in/extension RTE - uses TinyMCE (CDN too).
Fred is like NewsPublisher in that it is a frontend creating and editing tool for resources.
Fred does not handle TV fields at the moment as NewsPublisher does.

Fred, when saving the resources does it via AJAX.
When NewsPublisher is able to do this singular thing, it'd be the most complete tool in the planet!!!!!
(maybe I can sit down and figure out how, if Bob Ray does not beat me to it???)

Fred, Like Structures and modmore ContentBlocks, breaks the content field value into blocks for easy manipulation (drag and drop /predefinition etc etc)

For a free RTE in the Manager, I would use TinyMceWrapper. It takes a little work to set up, but is highly configurable.

TinymceWrapper v3 will completely eliminate all unnecessary hurdles in customizing this Extra.
