Hello ,
On my project there is one author writing an item and sometime another one edit the same item .
I would like to display that 2 peoples at the end of the item .
How to do this ?
Thanks for help

You will need to use an extrafield for the additional author.

Interesting , could you explain more because I know how to use extrafield but can't imagine how to bring second author info .
Thanks

You can use a link extrafield enter the link manually and render it in your overrides.
