Autocomplete in Combo

I need auto complete feature but without filtering data.
For example:
Combo contains the following items.


When user types letter ’t’, item “two” has to be selected but item “one” should be available in combo box. If user wants to select item “One”, he can scroll up and select without deleting typed letter ‘t’.

Please help me to achieve this functionality.

Could you please give answer in understandable format?


combo doesn’t provide such a functionality. But it is possible to show all options each time the list opens:

combo.attachEvent("onOpen",function(){ window.setTimeout(function(){ var text = combo.getComboText(); combo.setComboText(""); combo.filterSelf(); combo.setComboText(text); },1); })
