Magento 2 Layered Navigation is a filter in an eCommerce website. This feature can improve user experience, leading to a time on site increase and returning customers.

To maximize its efficiency, administrators need to understand it comprehensively. This post will help you know how to enable or disable, show or remove category filter, and custom Layered Navigation filter.

What is Magento 2 Layered Navigation

Magento 2 Layered Navigation is a sitemap and filter that allows users to search products easier based on category, price range, or any available product attributes. Store admins can set it up in the left column or in the bar above the page.

Because of layered navigation, users can search for suitable products in a time-saving way. For example, when a customer visits your website to look for shoes, he can use the filter with product attributes such as brand name, specific style, color, price.

How to Configure Layered Navigation in Magento 2

By default, Layered Navigation is enabled on the frontend. Thus, you don’t have to enable it, but you can show category filter in layered navigation. Let’s get started!

  • Firstly, go to Admin panel. Navigate to Store > Configuration > Catalog, choose Catalog.

+ Option 2: Automatic (Product counts)

+ Option 3: Manual

  • Set Display Category Filter to Yes to show the category filter on the layered navigation. To remove it from the navigation, choose No.

Finally, tap Save Config.

How to Disable Layered Navigation in Magento 2

Layered Navigation is by default enabled. If you want to disable it, there are 2 methods.

1. Method 1 

To hide product attributes in Layered Navigation, you can edit all attributes to non-filterable. To do this, go to Admin panel, then go to Store > Attributes > Product. You will see a list of all attributes. Your mission is to disable the one you do not want to display on the Layered Navigation with basic steps.

  • Click on the attributes you want to remove.
  • On the left, choose Storefront Properties. The Storefront Properties appear.
  • Look for Use in Layered Navigation, then switch it to No.

However, the subcategories will still be displayed in the layered navigation menu on the front end even though you disable all attributes with this solution. So, for example, if you have a category Clothes with subcategories Tops and Bottoms, on the frontend, the layered navigation block will display links to the subcategories within the category and cannot disappear completely.

2. Method 2 

To disable Layered Navigation entirely, you have no choice but to edit the code of the catalog.xml

Step 1: The path on your hosting account to the file that you need to modify is  public_html/app/design/frontend/base/default/layout/catalog.xml. In this file, find the code

<reference name="left">
<block type="catalog/layer_view" name="catalog.leftnav" 
after="currency" template="catalog/layer/view.phtml"/>
</reference>

Step 2: Change to

<!--<reference name="left">
<block type="catalog/layer_view" name="catalog.leftnav" 
after="currency" template="catalog/layer/view.phtml"/>
</reference>-->

Step 3: After you make the change, flush the Magento cache and refresh the frontend to see the result.
