when adding an additional tab to a tabstrip - the tabbing behavior does not work as it should when switching tabs use the html below: then select in the browser the dynamic tab - works ok then select in the browser the static tab - this results in both tabs being displayed HTML to reproduce: <!DOCTYPE html> <html> <head> <title></title> <link href="styles/kendo.common.min.css" rel="stylesheet" /> <link href="styles/kendo.default.min.css" rel="stylesheet" /> <script src="js/jquery.min.js"></script> <script src="js/kendo.all.min.js"></script> <script> $(document).ready(function() { $("#tabstrip").kendoTabStrip({ animation: { open: { effects: "fadeIn" } } }); var tabstrip = $("#tabstrip").kendoTabStrip().data("kendoTabStrip"); tabstrip.append({ text: 'Dynamic Tab', content: 'Dynamic Content' }); //var firsttab = tabstrip.select(); //tabstrip.select(firsttab.next()); //tabstrip.select(firsttab); }); </script> </head> <body> <div id="forecast"> <div id="tabstrip"> <ul> <li class="k-state-active"> Static Tab </li> </ul> <div> Static content </div> </div> </div> </body> </html>
