Hello @thanhquang0384,
Thank you for contacting us and using our plugin. The plugin is developed to stored the CF7 form data and display the data in back office. According to your requirement you need to mark the records as read and unread. It will be hard to identify which records are been viewed by the administrator or not.
This is something that requires additional development to handle your requirement. We suggest to contact a developer for customization of the plugin or you can contact us at ‘[email protected]’.
We will be happy to help you and provide you the quote for the customization required.
Feel free to contact us.
Regards,
