I created an AJAX filter for my WooCommerce products. This was working when I used Toolset Types, but now is not while using CPT UI (Custom Post Type UI) to create the custom taxonomy. When I filter, it will work but all the options don't work together. I even created a fresh install to test it out.
So, when I select a calorie taxonomy item (it brings up items in that option), then select a meal type taxonomy, it brings up items only in the meal type option, and then when I select the allergy taxonomy it brings up items only in that meal type.
I want them to work in conjunction so that clicking each item narrows it down and shows items that fall under all selected options.

javascript.js
/* Custom Shop Filter */
jQuery(function($){
$('#filter input').on('change', function() {
var filter = $('#filter');
$.ajax({
url:filter.attr('action'),
data:filter.serialize(), // form data
type:filter.attr('method'), // POST
beforeSend:function(xhr){
$('#loadingNotice').css('display' , 'block'); },
success:function(data){
$('#loadingNotice').css('display' , 'none');
$('#response').html(data);
}
});
return false;
});
});
I found a solution that works. Hoping to find a more elegant solution.
