Filter with Dropdown Menu

I am using CFDB 2.8 (just updated) in order to take advantage of the filter tools.

What I would like to do is have a select box that shows all of the “location” options for my results. Once selected I would like it to show only the information for that specific location. My thoughts were that I would do the following:

– Create multiple cfdb-table shortcodes with filter attributes for each location.
– Use JS or PHP and a select box to show the appropriate shortcode.

I’ve tried to follow the Filter directions here: http://cfdbplugin.com/?page_id=1073

I’ve added in the new attribute that was demonstrated:

filter=”strpos(location,Atlanta)>1″

I also added in the Add Actions and Filter Plugin and added the following code there:

require_once(ABSPATH . 'wp-content/plugins/contact-form-7-to-database-extension/CFDBPermittedFunctions.php');

cfdb_register_function('strpos');

Am I going down the right path? Any guidance to achieve my objective would be appreciated!
