drop down list scrolling

Hi,

Is there a way to create a dropdownlist that enables me to browse through its items by typing in more than one letter? For instance, if there are two words "mysql" and "mssql", I'd like the selector to jump to "mysql" in case I type in "my".

Thanks,
Nima

i found the javascript for it, see below. in addition i had to add the attribute onButtonPress="evalKey()" in the dropdownlist tag.

var tString = '';
var lsf = 0; // last successful index


function evalKey() {
// Global Variables
var i = 0;
var success = false;
var elem = event.srcElement;
var tLowElemText = '';
// Get the unicode char of the keypress
var eCode = event.keyCode;
// Check if it's a vaid ASCII Character
if (eCode == 27){
tString = '';
elem.selectedIndex = 0;
}
else if ( (eCode > 31) && (eCode < 122))
{
// Convert the Code to the corresponding character and add to searchstring
tString += String.fromCharCode(eCode);
// ... and perform the search starting from the top element in the listbox
while (success == false)
{
i = 0;
// Convert everything to lowercase; allows an easy comparison
var tLowString = tString.toLowerCase();
// Compose the regexp searchstring ...
var rExpr = eval("/^" + tLowString + "/");
while ((i < elem.length)&& (success == false) )
{
tLowElemText = elem.options[i].text.toLowerCase();
// success: Position the listbox on the (first) found element
if (tLowElemText.search(rExpr) != -1)
{
elem.selectedIndex = i;
success = true;
}
else {
i++; }
} // while i < elem.length
// if nothing is found in the entire list, the last character of the
//searchstring is removed to allow typing the correct 'next' character
if (success == false) {
tString = tString.substr(0, tString.length-1);
}
} // while success = false
}

window.event.returnValue = false;
window.event.cancelBubble = true;
}
