I may be mis understanding but here goes...
Your select menu is hidden, and any click you want it to display?
<!DOCTYPE html>
<html lang="">
<head>
<meta charset="utf-8">
</head>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load('jquery', '1');
</script>
<script type="text/javascript">
$(function(){
$('select').hide();
$(document).click(function(){
$('select').show();
});
});//END Doc Ready
</script>
<body>
<select>
<option>blah</option>
</select>
</body>
</html>
Then I realized you want the DDM to show up so i tried this ... and it did not work. Maybe this gives you an idea?
$(function(){
$('select').bind('blur', function() {
$(this).blur();
});
$(document).click(function(){
$('select option').trigger('blur');
});
});//END Doc Ready
