Prevent pasting in a jotform element text area.

If there is an essay text area, we don't want students to copy-paste essay into that text area. Is it possible to do this in Jotform?

Hello Queensford,

Unfortunately it is currently not possible to achieve this within the field properties. Please note that the only way to achieve your requirement is by downloading your form's full source code and adding custom css code. Please check the screenshot below on how to download your form's full source code:  https://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form

Thank you!
