Contractible Headers - modified

[amyth77]

Hey guys..
I was wondering, if the contractible header script (http://www.dynamicdrive.com/dynamicindex1/navigate2.htm) can be modified to act horizontally.

if i have 2 DIV side by side.. and the "header" of the left DIV is on it's right side, if I click that, the DIV expands/collapses to the side, instead of vertically as in the script.

When the left DIV expands, the right DIV collapses.. and vice versa..

Basically, the page will act like the collapsible frame, but here there are no frames.

Is there a script for this? Or can someone help me with it?

Thanks
