Why aren't my filters showing up?

Filters come from Shopify, not the theme. Wonpa renders whatever filters your store defines in Search & Discovery, so an empty filter list means none are set up yet.

Two things have to be true:

1. Install Shopify's Search & Discovery app and add filters under Settings → Search & Discovery → Filters. The theme shows the filters you define there.
2. In the theme editor, open the Collection section (or Search results for search pages) and confirm Enable filtering is on.

Note: Search & Discovery is a free Shopify app. Without it, a collection or search page has no filters to show, only sorting.

The filter panel also hides itself when a collection has no products matching any filter value.
