Does ContentBlocks support Redactor, TinyMCE, or CKEditor?
Yes, ContentBlocks will work with most rich text editors. We of course recommend Redactor, but the TinyMCE RTE and CKEditor packages are supported as well.
Important for TinyMCE users: if you encounter an infinite save loop and a javascript error "Cannot read property body of null", disable the contentblocks.remove_content_dom
system setting.
