Is the functionality to expand/collapse filters available with your Improved Layered Navigation extension?

The Improved Layered Navigation extension can use the expand/collapse functionality coming from the theme. On our demo, the filters are collapsible because Luma theme has this functionality inbuilt. To check whether your theme has the functionality, please, disable our extension temporarily and see if the default layered navigation filters can be expanded or collapsed.

How can I add a "Expand All" button to the layered navigation in Magento 2?

To add an "Expand All" button to the layered navigation in Magento 2, you can follow these steps:

1. Create a custom module or use an existing one to override the Magento_LayeredNavigation module.
2. Create a new JavaScript file that contains the code to handle the "Expand All" functionality.
3. Override the navigation.js file of the Magento_LayeredNavigation module in your custom module's requirejs-config.js file and add a reference to your custom JavaScript file.
4. Modify the renderer.phtml file of the Magento_LayeredNavigation module to add the "Expand All" button to the layered navigation.

In the JavaScript file, you can add an event listener to the "Expand All" button and use the toggle method to show or hide all the filter options. In the renderer.phtml file, you can add a new button element and attach an event listener to it that triggers the custom JavaScript functionality.

Adding an "Expand All" button to the layered navigation in Magento 2 can provide a more user-friendly experience for your customers, allowing them to quickly view and select all available filter options.
