Combobox scroll bar not working in IE

[keja]

We have added a extender for combobox to clear the input text if it does not exist in the item list of combo box. It works fine in all browsers.

 $.extend($.fn.combobox.defaults.inputEvents, {
            blur: function (e) {
                $.fn.combobox.defaults.keyHandler.enter.call(e.data.target);
            },
});

Laster we observed that in Internet Explorer (any version), the scroll bar for combo box does not work. Attached is the screen shot for your reference.

If we comment the a line of code in the function, scroll bar works well. However input text wont clear if it is not in the item list of combo box.

Could you please help us to achieve both ?

To limit the inputed values to the listed items, please set the 'limitToList' property value to true instead.

Code:

$('#cc').combobox({
  limitToList: true
  ...
})
