How to customise filters in product categories

My theme doesn’t offer filtering. My collection page are showing a default and random filter range which seems to be driven by the shopify platform and is based on tag words. How can I amend it? Is it possible to have different filters for each product categories. Here is an example: https://www.artisanoliveoilcompany.co.uk/collections/premium-olive-oils?filter.v.availability=1&sort_by=created-descending

I am not familiar with coding so easy fixed through the shopify backoffice would be ideal for me. Thanks in advance

Hello @Yacine2020

Your store is using Storefront filter. Thus you need to install the Shopify Search & Discovery app to manage the filters.

please follow this document >> https://help.shopify.com/en/manual/online-store/themes/customizing-themes/storefront-filters

If you need any help with the setup don’t hesitate to open an email thread with me.

Thanks

Many thanks
