I think the answer might be in here:
http://jquery-plugins.net/jquery-cascading-dropdown-plugin

I'll add the jQuery Zone to the question.

Ray,

thanks but no that does not help.

let me explain further...

the first dropdown  value is different regarding the value
but it always pulls the same second query

let us take this for example

Default Query 1:
Department: IT

Dropdown Query 2:
Department: (lists all departments)

The default is specific to the one person and if you want to change it then it lists all of them.

For the dropdown, you would probably want to use change http://api.jquery.com/change/

$('.myDropdown').change(function(){
    //do stuff

});

Open in new window


As far as populating the drop down, do you want to use ajax or a page refresh?  Does the drop down always show the same data?   There are a lot of ways to do this.  Can you detail what data you need to save if any from one drop down to the other.  Do you mean to have 2 chained dropdowns http://www.appelsiini.net/projects/chained

Can you please post a link to a web page (any page) that demonstrates this?  I don't quite follow the description, but if I see it in action maybe I can show you how it's done.

I got it working

here is the code

if ( $objResult["FIELD"]  == $row ["FIELD"] ) {
	echo '<option selected value="' . $objResult["FIELD"] . '">' . $objResult["FIELD"] . '  </option>'; 
}
else { 
	echo '<option value="' . $row['FIELD'] . '">' . $row['FIELD'] . '  </option>'; 
}
