Hi Customer,
Thank you for contacting Syncfusion support.
The FlowDirection property of the control is used to display the control and its elements in the mentioned flow. At present our SfRichTextBoxAdv does not supports the FlowDirection property.
However, our SfRichTextBoxAdv control supports the Right to left flow for the document contents like paragraph, table and list in Docx, Doc, RTF or XAML formats from v15.4.0.17. You can set the Right to left flow for the paragraph (similarly for table from table properties dialog) directly from the ribbon option.

Could you please provide us the following details? So that we can analyze further in-line with your requirement and provide you the proper solution at the earliest.
1. Do you need Right to left flow preservation in HTML format (.html files) import or export?
2. What is the Syncfusion Essential Studio version you are using now?
Regards,
Dilli babu.
