WooCommerce: Product Category Filter @ Shop Page

There is already a widget that allows you to place a “Product Category Dropdown” in your sidebar areas. The problem is that lately, sidebars have become kinda 1990. So, what if you want to place a “Category Select Box” anywhere in your WooCommerce website, and (in this case study), exactly on the Product Category pages, so that you can switch from one category to the other?

Well, in this snippet you will learn a lot of things. For example, the wc_product_dropdown_categories() function magically displays a category dropdown, while the wc_enqueue_js() function allows you to inject jQuery (responsible to trigger the category page redirect).

Here’s my “Product Category Switcher” in action on the Product Category pages. As soon as a different category is selected, a redirect take place.

PHP Snippet: Show a Product Category Switcher and Redirect Upon Selection

Please note in the “location.href” section you have to make sure you enter the correct permalink base for product categories, otherwise you will get error 404. In this case, I’m using the default product category permalinks, “/product-category/“.

function bbloomer_filter_by_tag() {		
	if ( is_product_category() ) {		
	wc_enqueue_js( "
		$('#product_cat').change(function () {
			location.href = '/product-category/' + $(this).val();
	" );

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101

  1. If you get 404 when selecting the “select category” from drop-down try this it will also show on shop page as well

    add_action( 'woocommerce_before_shop_loop', 'bbloomer_filter_by_tag', 31 );
    function bbloomer_filter_by_tag() {      
       if ( is_product_category() || is_shop() ) {      
       wc_enqueue_js( "
          $('#product_cat').change(function () {
    	  	 if($(this).val() != ''){
    		 location.href = '/product-category/' + $(this).val();
    		 location.href = '/shop/'
       " );

    1. Hi Vishven, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  7. Hi Rodolfo,

    Thank you for this snippet!

    May I know how to add a little space in front of it please?

    See: https://d.pr/free/i/dEgpdx

    1. Sorry, no. But you can just use simple CSS margin

  8. Hello
    Great idea. I found one problem though. It does not work in my mobile. Also Is there a shortcode to add it wherever you want ? for example this should be in the home page too (in my case) that is not the shop page

    1. Hey Yiannis, thanks for your feedback! Maybe you have JavaScript disabled on mobile? Otherwise try to clear its cache. The shortcode, yes, it’s possible, but it’s custom code I’m afraid. Thanks!

      1. Hello
        I don’t have js disabled in my mobile and I open the page as private in iPhone which means that there is no cache !! I still cannot see the menu in the mobile

        1. Disable all plugins but Woo and switch theme temporarily. Does it work?
