Add the data which are not available in the list

[codeworriors45]

Hello,
I am having the list of email ids and adding the selected email ids into an array, but now the requirement is I also have to give the option to allow the user to add email ids that are not available in the ng2-completer list.

Is there any way to achieve this using ng2-completer? or any other suggestion to implement both funcationloity?

TIA.
