>The headings tags will show up with the css formating in the font format dropdown and all >the other styles will show on the page as they add content or choose lists etc... If you >want them to be able to choose styles and for them to show in the styles dropdown, you >will have to add those to the xml file.
This makes no sense to me? ..all the other styles will show on the page as they add content..? How else would this be other than in the styles dropdown?
