jQuery Tools - make tabs collapsible

Question

I'm using a basic integration of jQuery Tools "tabs" function and it's working perfectly for me, but the one thing it seems to lack over jQueryUI is that there's no way I can find to make the tabs collapsible. By that I mean all you need to add is

collapsible:true

to the jQueryUI tabs function.

Does anyone know of a way I could append code to the following jQuery Tools statement to make the tabs collapsible?

Any advice appreciated!

$("ul.main_tabs").tabs("> .mainpane");
