I'm not sure if I understand your question correctly.
Do you want to embed a form in your asp.net website? If so, you can follow the steps provided in this guide: http://www.jotform.com/help/34-Adding-a-Form-to-a-Web-Page
Also does it support RTL?
Yes, you can read more about multilanguage forms here: http://www.jotform.com/help/298-How-to-make-your-forms-multilingual. I'm suggesting this guide because you need to create your form in English first and then translate it into another language to prevent the form from being blocked by our anti-phishing scanner.
Let us know if you have further questions.
