Hi Ma,
Thanks for your suggestion.
We have promised to provide DynamicHeight mode support only to SfAccordion control for 2019 Volume 2 SP1 release. If you face this kind of issue in SfTabView control or any other control, please explain your issue in detail with respective controls, so that we could forward the reported query to concern team and get back to you with details.
Regards,
Jagadeesan
