can this code be shortened??

can this code be shortened??

Hi,

I'm new to JQuery (and javascript in general) and just created the following code which works fine. When a user clicks the #category1 element, certain div elements (itemA..ItemN) are either hidden or shown. Based on what the code is doing, would there be a better (shorthand?) way of writing this code?

Thanks!

$(document).ready(function() {
        $('#category1').click(function() {
                // hide/show relevant divs
                $('.itemA').show();
                $('.itemB').show();
                $('.itemC').hide();
                $('.itemD').hide();
                $('.itemE').hide();
                $('.itemF').hide();
                $('.itemG').hide();
                $('.itemH').hide();
                $('.itemI').show();
                $('.itemJ').show();
                $('.itemK').hide();
                $('.itemL').hide();
                $('.itemM').hide();
                $('.itemN').hide();
        });
});
