I am using MVC 5 with Twitter bootstrap. Recently implemented an autocomplete for a list of Cities. The problem is that if I resize the window while the autocomplete list is shown it remains in a fixed position instead of being below the input text field.

You could include javascript to detect the browser resize and close the Autocomplete box when that event is triggered:
$(window).resize(function() {
$("#myAutoComplete").autocomplete("close");
});
