Collapsiblock module - can I have horizontal expanding tabs instead of vertical? Collapsiblock: http://drupal.org/project/collapsiblock

I am looking for a way to allow the sidebar blocks to be collapsible left-to-right instead of top-to-bottom using the Collapsiblock module. It would basically be a way to hide the left and right-column blocks until someone clicks the tab, after which the block would expand to the width of the column. It seems as though it should be a fairly straightforward change in the JS file, but I cannot figure it out. Can anyone here provide any insight into this?

Thanks!
Search slideUp and slideDown in collapsiblock.jsand replace with animate, for example:

$(this.target).animate({width:'toggle'},slidespeed);
