Editor.DisableAutoFormatting Property
By default Cute Editor will carefully analyze all of your HTML code and begin correcting all errors automatically. What you get is professionally presented code, properly reformatted and ready for use. If you want to preserve the formatting of existing HTML, you can turn this feature off by setting Editor.DisableAutoFormatting property to "true".
