Hi Michael,
Sorry for the inconvenience caused. We require some more details to provide correct solution so can you please provide additional details on this.
1) Confirm us whether the platform is MVC (classic)?
2)The RTE height and width has to be set to the automatically depending on text value. Is this your requirement?
3)Can you please share code snippets or sample to proceed further on this?
Regards,
Keerthana.
