How to customize RTE plugin for link option in the Content Fragment RTE AEM6.5?
We are trying to customize the hyperlink option in the content fragment RTE.

Need to add a text field and a custom drop similar to Target. Basically we need authors to select custom name which can be added as a class attribute in the <a> tag. Example: <a title="google" href="http://www.google.com" target="_blank" class="style-as-button">google</a>
Note: We have overridden the StyledTextEditor to add more options to the paraformat and also include misctools.
Kindly let me know the possible ways to achieve this. Thanks
