MDI Forms with JavaScript?

Hello Everybody.

Is it possible to open a child window inside a parent window,

non visible in the task bar and with the minimize functionality

that minimizes it in the bottom left corner. Something like

the MDI forms found in VisualBasic or Java.

I found something about dragable layers, but these layers

have no minimize functionality and can't have more that one

instances. Is there any way that i can do this?

Thanx.
