Show Filters on all Category pages Opencart v2
Here is another module which helps the opencart users to list filters automatically on all category and sub-category pages.
By default one has to assign filters to each category page in opencart v2+, which is tedious and time consuming. With this module you need not assign any filters to the category pages, filters assigned to products show up automatically on the relevant category pages.
Both vqmod and ocmod versions are provided, hence it is easy to use as per the need.
You can find this free module on opencart. Download on official opencart page
