it's a javascript problem and not a java one :

add value :

var name = 'YOUR_NEW_OPTION_NAME';

var value = document.getElementById('YOUR_TEXT_INPUT_ID').value;

var option = new Option(name,value);

document.getElementById('YOUR_DROP_DOWN_LIST_ID').options[(document.

getElementById('YOUR_DROP_DOWN_LIST_ID').length)] = option;

[u]remove a value:[/u]

if( document.getElementById('YOUR_DROP_DOWN_LIST_ID').selectedIndex >= 0){

document.getElementById('YOUR_DROP_DOWN_LIST_ID').options[document.getElementById('YOUR_DROP_DOWN_LIST_ID').selectedIndex]

}

While adding a value to drop down list, the statement:

document.getElementById('YOUR_DROP_DOWN_LIST_ID').options[(document.

getElementById('YOUR_DROP_DOWN_LIST_ID').length)] = option;

Adds an Object to the Drop Down list. But I required to add a value to it.

For remove: is that statement in a condition works properly.
