WooCommerce Custom Taxonomies: The Easy Way to Display Extra Product Data & Filters
WooCommerce comes with various fields for storing product data. There’s the product name, long and short description, price, images, stock, weight, dimensions etc. But what happens if you want to store and display extra product data, such as WooCommerce custom taxonomies?
I’m going to tell you how to create WooCommerce custom taxonomies for products. We’ll look at the difference between WooCommerce custom fields and taxonomies and which to use for different types of product data. I’ll also show you how to add custom taxonomies to store extra information about WooCommerce products.
Finally, I’ll teach you an easy way to display products with the WooCommerce custom taxonomies in a searchable, sortable table. You can show the extra fields on a normal WordPress page, on your shop or product category pages, or on the single product detail page. You can even let customers filter by custom taxonomy, making it easier to find your products.
And best of all, you can do all this without writing a single line of code!

What’s the difference between WooCommerce custom fields and taxonomies?
WooCommerce custom fields are used to store arbitrary, one-off information about a product. A custom taxonomy is for grouping things together.
This is reflected in the way you add custom fields and taxonomies for products in the WordPress admin:
- Custom fields appear in the main column of the Add/Edit Product screen. This is where you add other unique product data such as title, description, price etc.
- In contrast, custom taxonomies appear in the right hand column under the product categories and tags. Like categories and tags, each WooCommerce taxonomy term should be selected for multiple products.
When should I use custom fields & when should I use a WooCommerce taxonomy?
Once you understand the difference between a WooCommerce custom field and taxonomy, it becomes more obvious when to use each one.
As a rule of thumb, you can decide between custom fields and taxonomies by asking yourself: “Is the data I am adding unique to each product, or does it apply to multiple products?” If the data is unique for each WooCommerce product then you need a custom field. If you want to select the same value for several products and use it to group them together (e.g. via a product filter) then you need a WooCommerce taxonomy.
Here are some examples to help you choose:
- WooCommerce clothes store displaying the color of each product. If you’re selling clothes in WooCommerce, you’ll probably want customers to be able to find products by color. You’ll have multiple products of each color. By creating a WooCommerce custom taxonomy called ‘Color’, customers can filter the list of products to find the color they like. This wouldn’t be possible with a custom field.
- WooCommerce second hand site storing ‘condition’ information about their used products. If you’re selling used goods like eBay, you’ll need a field to store details of any damage etc. The description of each item’s condition will be unique to that product, so you should create a WooCommerce custom field.
- WooCommerce product directory with a large product database. WooCommerce directory-style websites with large numbers of products often list extra product data within the directory listings view. For example, a book directory might include data for author, publisher and year.
And if you’re feeling really clever, you can use both together!
To use the 2nd example above, a store selling used goods might want a WooCommerce taxonomy called ‘Condition’ AND a custom field called ‘Condition Description’. The ‘Condition’ taxonomy would include the terms “New”, “As New” and “Used”, which apply to multiple products.
You could create product filters so that customers can narrow down their search based on the overall condition. The ‘Condition Description’ custom field would provide unique information about the exact condition of the product and any damage.
Video tutorial – WooCommerce custom fields & taxonomies
In this video tutorial, you can watch me creating WooCommerce taxonomies and custom fields, and displaying them on a WordPress website. There are also full written instructions below:
How to create a WooCommerce custom taxonomy
The best plugin to create a custom taxonomy for WooCommerce products is Custom Post Type UI. With over 400,000 active users, it’s a hugely popular plugin and is 100% free too!
As well as creating custom post types (which you don’t need to do), Custom Post Type UI lets you add taxonomies to an existing custom post type. This is what you need, as WooCommerce products are a custom post type in WordPress.
You can also create WooCommerce custom taxonomies with the free Toolset Types plugin. I’ve used Custom Post Type UI in this tutorial, but they’re both good options. Whichever plugin you use to create your product taxonomies, you can display them in the front end using WooCommerce Product Table.
Here’s how to use Custom Post Type UI as a WooCommerce custom taxonomy plugin:
- Go to Plugins > Add New in the WordPress admin and search for ‘Custom Post Type UI’.
- Install and activate the plugin.
- Go to the ‘CPT UI’ section in the left of the WordPress admin and click on the ‘Add/Edit Taxonomies’ section:
- Add the Taxonomy Slug (ideally 1 word, lowercase).
- Add a plural and singular name (label) for your WooCommerce custom taxonomy. This will only appear in the WordPress admin.
- Attach it to the Products post type.
- Click ‘Add Taxonomy’.
- Now go to the Edit Product page and you’ll see the custom taxonomy on the right hand side, under the categories and tags. Add 1 or more taxonomy terms for each product, just like with standard product tags.
Displaying WooCommerce custom taxonomies in the front end
Normally, the only way to display custom taxonomies for WooCommerce products is to edit the template files for your and product archive pages. This involves a bit of coding knowledge.
The good news is that there’s a handy plugin to list products in a table along with extra data such as WooCommerce custom taxonomies. It’s an ideal way to display products with extra information as everything is presented in a structured tabular format. You can add product tables to any WordPress page, to your main WooCommerce shop or product category pages, or even to the single product page.
The plugin for displaying custom taxonomies is called WooCommerce Product Table. It supports all the usual WooCommerce product data, plus custom fields and custom taxonomies. Each item of product data is listed as a separate column in the table.
Customers can search or sort the table by any product custom taxonomy term. They can also filter by taxonomy via handy dropdown lists above the table. You can even create WooCommerce tables that only contain products with a specific taxonomy term.
This is much easier than modifying your WooCommerce template files. And even better, you get all the other benefits from using product table layouts such as improved conversion rates.
How to create a product table with WooCommerce custom taxonomies
It’s easy to set up WooCommerce Product Table with all the extra product data.
Install WooCommerce Product Table
- Get WooCommerce Product Table. Download the plugin using the link on the order confirmation page and email.
- In the WordPress admin, go to Plugins > Add New. Upload the plugin files and install and activate the plugin.
- Go to the plugin settings page: WooCommerce > Settings > Products > Product Table. Enter your license key and click Save. You can also choose some default settings which will be used for all your product tables. This saves having to create such complex shortcodes later on, as these settings will be used automatically whenever you create a product table.
Now, the product table plugin is set up. The next step is to add product tables to your website. Use one of the following methods, depending on where you want to display WooCommerce taxonomies.
How to show WooCommerce taxonomies on a standard WordPress page
- Install WooCommerce Product Table.
- Go to edit any page in WordPress. This is where you’ll add a table listing some or all of your products with the taxonomies.
- Enter the shortcode:
- This will display all your products in a table with standard data. Next, you need to expand the WooCommerce Product Table shortcode to include your custom taxonomies and any other extra data. Each piece of product data will appear in its own column within the table.
There are full instructions for all the available columns in the plugin knowledge base. To get you started, here’s an example of a product table with columns for name, a custom field called ‘Condition’, a custom taxonomy called ‘Color’, price and add to cart button. You need to know the custom field name and the taxonomy slug. You chose these when you created your custom fields and taxonomies earlier in this tutorial.
How to display custom taxonomies on the WooCommerce shop page or product category archive
Most people add WooCommerce Product Table to normal WordPress pages. They include these pages in their website navigation structure instead of linking to the built-in WooCommerce category archives.
If you prefer, you can add product tables with custom taxonomies directly to the main WooCommerce shop page or category pages. This is a bit trickier, as you need to add the product table shortcode to the template file in your theme. To make it easier, the plugin knowledge base provides instructions on how to do this.
- Install WooCommerce Product Table.
- Follow the instructions for adding product tables to the shop or category archive template.
How to show WooCommerce custom taxonomies on the single product page
- Install WooCommerce Product Table.
- Go to edit the product where you want to display custom fields and taxonomies.
- Add a product table shortcode to the Short Description field.
You can use this shortcode as a starting point.
[product_table columns="cf:size,tax:fabric,stock" page_length="false" search_box="false" reset_button="false" totals="false" include="19" links="none"]
This lists the data for the current product. There are columns for a custom field called ‘size’, a custom taxonomy called ‘fabric’, and a stock column. I have hidden elements such as the search box and product name, which aren’t needed on the single product page.
Replace the sections of the shortcode in red as follows:
- cf:size – Replace ‘size’ with the name of the custom field you want to display in the table. Remove this part of the shortcode if you don’t want to display any custom fields. (More information here.)
- tax:fabric – Replace ‘fabric’ with the name of the custom taxonomy you want to display on the product detail page. If you want to display multiple custom taxonomies, that’s fine too – just add each one separated by a comma. (More information here.)
- include=”19″ – Replace the number 19 with the ID of the product that you want to show the data for. You can find this by going to the ‘Edit Product’ screen in WooCommerce. Look at the URL at the top of your browser window. For example, my example product has the URL /wp-admin/post.php?post=19&action=edit. This tells me that the ID is 19. Do the same and find the ID for your product.
- You can also make any other changes to the product table, for example by adding or removing columns. See the full list of options in the knowledge base.
Now save the product and view it. You will see a simple WooCommerce table in the short description field, containing the custom taxonomy and other product data.
Display WooCommerce taxonomies in a filter
You can also list WooCommerce custom taxonomies as a filter dropdown above the product table.
You can add a separate filter for each custom taxonomy (plus other data such as attributes, variations, categories and tags – instructions here).
This is how to add 1 filter with the ‘colour’ taxonomy:
[product_table columns="name,cf:condition,tax:color,price,add-to-cart" filters="tax:color"]
Create tables listing products with a specific custom taxonomy term
By default, your WooCommerce product tables will list all the products in a table. This is perfect if you plan to have a single table listing your entire WooCommerce inventory.
You can also create product tables listing products from a specific category, tag, custom field or WooCommerce custom taxonomy term.
Here’s an example to get you started. To do it on your own website, you will need the custom taxonomy slug AND individual term slug. In this example, we’re using a custom taxonomy with the slug ‘color’ and a term with the slug ‘red’. We need to include both in the product table shortcode:
[product_table columns="name,tax:color,price,add-to-cart" term="color:red]
You can list WooCommerce products with multiple custom taxonomy terms. See the documentation for full details.
