CKEDITOR will automatically connect elements that have an attribute by default contenteditable="true". Do you want to disable CKEDITOR inline editing, or you can do this in the global configuration.
CKEDITOR.disableAutoInline = true;
I prefer to do this in the code, rather than in the config, so if someone else uses it, you will not ruin them.
Based on your comment on including CKEDITOR. This is pulled from CKEDITOR 4 docs.
Enable inline editing
Inline editing is included directly in HTML elements through HTML5 contenteditable.
