Hi Srinivask,
Thanks for responding the query.
The answer is very helpful but in my scenario for "mail text" the user wants an interface( any screen) where he/she can edit the text that is sent to the email id of customer. The user wants to edit the mail on run time and also the option to cancel the mail if he/she does not want to send the mail. After clicking on the Email field(that contains the email id of customer) on complaint creation page ,user wants to open another page automatically that contains some basic information about complaint like complaint no, remark etc. and also wants the option to add anything else in the body of mail and then either to send or cancel the mail.
Please help to make the text of email editable by the user at run time.
Thanks and best regards,
Kavita chaudhary
