jquery treeview highlight only current item
===

Need a little help: I'm using jquery treeview plugin (this one: http://bassistance.de/jquery-plugins/jquery-plugin-treeview/). And I'd like to do highlighting the current item. I'm doing it this way:

CSS:

    .filetree li .clicked {
        font-weight: bold;
    }

And JS code:

    $('li').live('click', function(event){
        event.stopPropagation();
        console.log(this.id);
        $('.clicked').removeClass('clicked');
        $(this).addClass('clicked');
        return false;
    });

Everything works fine, but all items are highlighted together with its child elements, and the root elements are not highlighted in a whole. 

How can I make a highlighting of only current item? Thanks in advance!
