        .ztree li span.button.switch.center_docu {visibility:visible; width:16px;}
        .ztree li span.button.switch.bottom_docu {visibility:visible; width:16px;}

.ztree li button.switch.roots_docu {visibility:visible; width:16px;}

.ztree li button.switch.center_docu {visibility:visible; width:16px;}
