On one of my Coldfusion forms, I have a dynamic list box that gets populated by using cfquery - my question is, how can I allow the user to add a selection to the list box if their choice is not listed?  Thx!

if their choice is not listed in the listbox and the list is results  from a query....
that choice needs to be added to the database and included in your query.

The listbox with new options is an old general question.
The best choice is to have one Option in the list the allows the user to use a separate Input field for not listed value.
Name that Option: Other
On the server side check if Other selected then use OtherInput value.

Or in other words: same reason that you cannot define Blinking text in style definitions you cannot have Editable select options.
Of course there are enough geeks out there to give you both: blinking editable options; but I assume that was not your question <|;-)

<!--- main form page --->
<!--- note: Certification is a text field --->
<cfquery name="cert" datasource="myAccessDSN">
SELECT Certification
FROM Certification
ORDER BY Certification
</cfquery>
<script>
function showAddPage() {
window.open('addNewCertification.cfm');
}
</script>
<cfform action="somePage.cfm" method="post">
<cfselect query="cert" name="Certification" value="Certification"
multiple="yes" size="5"/>
<a href="javascript:showAddPage();">Add New</a>
</cfform>

<!--- popup page: addNewCertification.cfm --->
<form action="addNewCertification.cfm" method="post">
Certification code: <input type="text" name="Certification">
<input type="submit">
</form>
<cfif IsDefined("form.Certification")>
<cfinsert datasource="#data_source#" tablename="Certification">
<script>
if (window.opener) {
window.opener.location.reload();
window.close();
}
</script>
</cfif>
