Thanks Adam,
I managed to get it working... although I have a few issues (I am using dnn 3.2.0)
1. The spell checker doesn't seem to work (I get a popup with an asp.net error message), I get the same issue if I try to edit templates from the templates dialog box.
2. What is the difference between 'Css Class' and 'Inline Styles' in the drop downs
3. I want to be able to control the Css Classes which appear in the drop down and am looking for the simplest possible solution. I notice that by default it includes all dotnetnuke styles. If I want to limit this list to styles contained in a custom.css file how would I do this (i.e. disable default behaviour of populating dnn css classes)?
Cheers
Adam
