Sliding Panel over Mailbox

[riju123]

Hi all ...
i add something new to the Zimbra Mailbox .
Its a sliding panel over the mailbox which is gonna look like the attached picture.
If i press it a panel is supposed to come up of size around 100 x 100 .

Till now , I am able to create a Sliding panel separately , but the problem am facing is attaching it to the MailBox . So far i did was playing around with the launchZimbraMail.jsp and a few more jsp-s but nothing worked out .
I hope what am trying is possible ...
Please Help .

Thanks in Advance
