Yes you can use that . just made a style node and give the name of all css class that you want to add in drop down
Thanks for your reply.
I have tried that way and I am getting the css class name in the drop down. The problem is, the styles are applied when I view the content within the “Richtext” editor.
When I click on ok button of the “Richtext” editor, the styles are disappearing in the web page.
Do you know how to resolve this issue ?
