I want to add my personal tag into the choice of the attachment, like yflickr zimlet.

I want to give at user the possibility to choose an other repository where take the file which must be attached.

Now, I've this question/problem:

1) How I can modify the panel of attachment file

2) Where can I find the way Zimbra manages attachments (documentation)

3)Last question : Can I get information from a jsp class ( I need this because my "repository" is populated dynamically

Thank's for the help
