I want to close my combogrid from a toolbar button (x). I found a way doing this by putting css('display', 'none'). However this way it's not possible to reopen combogrid without having the dropdown recreated. 
, toolbar: [{ iconCls: 'menu-small' }, { text: "<div id='abc'>abc</div>" }, {
                        text: "x", onClick: function () {
                           var el = $(this).closest('.combo-p');
                           el.css('display', 'none');
                        }
                     }]Any suggestions?
