Yes, please modify toolbar configuration files which can be found under CuteSoft_Client/CuteEditor/Configuration/Autoconfigure folder.

 

   <item type="dropdown" name="CssClass" width="80" RenderItemBorder="true" text="[[CssClass]]" command="CssClass" />
  <item type="dropdown" name="CssStyle" width="50" RenderItemBorder="true" text="[[CssStyle]]" command="CssStyle" />
  <item type="dropdown" name="FormatBlock" width="60" RenderItemBorder="true" text="[[Paragraph]]"
   command="FormatBlock" />

Thanks.

You should be aware that this really doesn't work will with IE7 Beta 3.  The space for the dropdown increases as I change that value, but the dropdown itself stays the same size and looks a bit silly.

I can send screen shots if needed (email me)
