This may not definitively answer the question, but I hope this helps you in finding the most appropriate solution. And actually, I’ve tried the super simple plugin at the bottom with your HTML and JS, and everything worked fine for me. This is my first attempt to write a plugin and I get an error …

Are you familiar with jQuery? You’ll want to post the term to a admin-ajax, and use the response to populate the second select. Here is the codex documentation: http://codex.wordpress.org/AJAX_in_Plugins A loose example for your situation: $first_term = $(‘#states’); $name = $first_term.children(‘option:selected’).text(); var data = { action: ‘tag_slug’, slug: $slug }; var ajaxurl=”wp-admin/admin-ajax.php”; $.post(ajaxurl, data, function(response) …
