WooCommerce: Display a Product Categories Dropdown Select

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).

You can demo this snippet on this live WooCommerce website of mine: A Piece of Sicily – Sicilian Crafts Category. Enjoy!

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/“.

add_action( 'woocommerce_before_shop_loop', 'bbloomer_filter_by_tag', 31 );

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

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.

  1. 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

  2. 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
    Yiannis

    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!
