Adam:
Editor.EditorWysiwygModeCss Property
Specifies the location of the style sheet that will be used by the editable area. Multiple Style Sheets are supported. Example EditorWysiwygModeCss="example.css,~/portal.css,/default.css"
Also make sure you set Editor.AutoParseClasses Property to true.
How come when I do this (set Editor.AutoParseClasses = true), the custom dropdown I added no longer appears? I have a dropdown called ["styleSheet"] that I added to the dropdown ToolControls.
The Css Class list is populating the classes from my file, but my dropdown is gone!?
