[jQuery] how to loop over checkboxes and hide the UNchecked ones?

[Priest, James (NIH/NIEHS) [C]]

I've got a series of topics - each with a list of checkboxes.

Topic
0 item 1
0 item 2
0 item 3

When the user clicks the topic - I have the checklist show/hide using
toggle(). What I'd like is when the list closes - the 'checked' items
remain visible.  

Topic 
X item 2
X item 3

I'm struggling with how to loop through the list of checkboxes??  My
attempt to use .each() isn't working??

        $('h3').click(function() {
                // $(this).next().toggle("fast");
                // $(this).toggleClass('down').toggleClass('right');


                $('input:checkbox').each( function() {
                        var checked_status = this.checked;
                        if (!checked_status)
                        {
                                $(this).hide();
                        }
                });
        }); 


Thanks,
Jim
