We regularly get questions about having the ability to add classes and IDs to links and images, as well as title tags for links. While we keep Redactor as simple as possible out of the box, it’s really easy to get some more features enabled through the redactor.advAttrib setting.
Advanced attributes enables a couple of different panels when editing links and images, allowing you to add images classes, IDs and titles where that would not be possible previously.
This feature is both available for Redactor 1.5 and 2.0.
