Login with Dropdown user list

[stonysleep]

I found this thread:
http://www.roundcubeforum.net/index.php?topic=9608.0
And want to achieve the same thing as the poster there on my RoundCube installation but I can't find the autologin plugin that is mentioned in the answer
I have 3 usernames that I would rather select from a dropdown list than typing in
Is it possible and what would be the best way to do it?

Thanks

You'd need to make the form or also modify the login form. The autologon plugin should be in <RC root>/plugins/autologon.

Thanks
Thought there might be an easier way but sounds like I'll have to build the form
