[RESOLVED] ListSearchExtender but in a textbox

[sapator]

Hi.
Ok the AJAX ListSearchExtender will manipulate listboxes,dropdownlist etc.
In another discussion here i presented a filter that does this exactly as i want(and better imo).
What i need to know is, if there is some mechanism that you can type in a textbox and bellow you get the data that you want(p.e. typing a will present "aardvark","afoul","ant" ,typing an "f" after the "a" will only show "afoul", you get the point) not in a predefined listbox with data but possibly in some other sort of(ajax?) control.So in sort the data will be shown when you start typing.
A simple example is a forum that you go to the search option and you want to find posts by a user.When you start typing you get a list below with matching user names.So this is doable at least with php sites using JS.So any help.

P.S. This filter is for future usage so i don't need a fast "alternative".And i think it's JS time again ( ).

Edit.Come to think of it.Google does this but in much higher extend.
