CKEditor 4 - How to quote with the author and link to the post (or just with the author)?
Those. so that there is a "Reply" button next to the post and the entire text of the post and the link to the post go down to the CKEditor.
I know approximately that it is necessary to register the id of the blocks through JS, where the author, the text of the post and the link are located and combine them together.
But how?
