A JavaScript alert or dialog with a combo box
<p>This looks fairly simple, but 30 minutes of googling took me nowhere. :-(</p>

<p>How do I create a simple JavaScript dialog / alert with a combo box so my user can select a value before submitting? I am using this for a rejection reason so user clicks on reject button and must select a reason from a combo box inside an alert / dialog popup window before submitting.</p>

<p>Thanks!</p>
