Where to start
Filter configuration is quite cumbersome task in Opencart. But patience will be rewarded with an improved UX of your store. Let's go through basic filter configuration steps.
1) Create filter groups which you would like to have in the store
2) Link filter groups to existing options on the option edit page
3) Generate filters for products on the product list page
4) Generate filters for categories on the category list page
5) Add the filter section to categories and the search page on the 'Layouts' menu
6) Optionally enable the price search section on the extension settings page
7) Check the results.
If everything works great and you like the results, you can configure automatic filter rebuild. This is configured as a task of the task scheduler module. The task scheduler lite module is bundled with the extension and provided for free.
