Hi, Is it possible to copy and paste "To" and "CC"

i'm not exactly sure what you mean by "copy and paste" - do you mean like allow the user to copy/paste email addresses into text fields on a form?

you are right... user should be able to copy/paste email addresses into email field of a form.

You can allow users to paste email addresses separated by a standardized delimiter (e.g. comma, semi-colon, and/or line break) into a paragraphField, then split that (single) text into an array of strings, each of which could be an email address. You could parse similarly for usernames, if pasting is preferable to picking users.

Does this solve your question?

This can be done a couple different ways, it completely depends on your use case. You could have text fields and put validation/formatting on the field.

Basically we already have To and CC field(of email type) in a user input form in Prod, User just needs to copy paste the email id's into these fields.

Is it possible to I can modify to these fields so that I will be able to copy paste id's?

Jorge do you happen to know if there is a plug-in that does full and complete email validation? The solutions I have seen in my work thus far have not covered all possible email addresses.

I don't believe that there is a plugin that does full and complete email validation. If there is, I haven't used it.

@Marky:
there's not a very solidly defined standard for what constitutes a "valid" email address, so there's probably no single rule that will be 100% correct. But I have previously written and out-of-the-box compatible expression rule which should do pretty well for appian email address compatibility; we were just talking about this yesterday on this thread: https://forum.appian.com/suite/tempo/entry/e-204914 - also someone posted a potential solution that uses the regex plug-in.

Is there any way I can copy paste email addresses? to the fields TO and CC fields of type email?

What version of Appian are you using? Are you using the SAIL interface?
