Allow selections not in list (for the web)

One of the neat options with drop down selections in Notes, is the ability to let people type an option that is not in the list. This helps build dynamic lists.

Here is some javascript to use to get this working on the web:

function changed(el, cmp, pmt){
if(el.options[el.selectedIndex].value==cmp) {addoption(el, pmt);}
function addoption(el, pmt){
var txt=prompt(pmt,'');
if(txt==null) {return;}
var o=new Option( txt, txt, false, true);

You can either put this in an included javascript file or wrap it directly inline.

Then you can call it using the onchange event for your selection field:

onchange="changed(this, 'New Group', 'Please enter new group:')"

Where "New Group" is the text you want to trigger the prompt for the text and "Please enter new group" is the prompt you want to display.
