Kowal Tags Bar (Amasty Shopby Compatible)

Kowal Tags Bar adds, above the product listing (category or search results), a tag bar that works as a quick filter for a single attribute of type dropdown (select). The solution is independent of the layered navigation styling. Tags are always displayed above products, which works great in stores where customers expect marketplace-style quick filters.

Key features:

Dropdown equals single selection (simple behavior: only one tag can be active at a time).
Hide empty tags: the module shows only options that have results in the current category and its subcategories (the active tag always remains visible so it can be disabled).
Two link modes:
- Default (Magento): standard parameter ?tags=ID
- Amasty: fetches SEO URLs from the filter layer (Shopby) and uses them in tags.
Appearance configuration in the admin panel: font, background and border colors (also separately for the active tag), plus custom texts like Tags: and All.
Diagnostic logging (helps with deployment on custom themes or non standard filter configurations).

The module is ideal for stores with a large product catalog, where customers first choose a style, collection, or use case, and only then refine other filters.

Question:
Czy moduł działa bez Amasty?

Answer:
Tak. W trybie Default generuje standardowe linki Magento (?tags=ID).

Question:
Czy można wybrać kilka tagów naraz?

Answer:
Aktualnie nie — celowo jest to pojedynczy wybór (dropdown), aby UX był prosty i szybki.

Question:
Dlaczego nie widzę niektórych tagów?

Answer:
Moduł ukrywa opcje bez wyników w bieżącej kategorii i podkategoriach. Jeśli tag ma 0 produktów — nie jest wyświetlany

Question:
Czy tagi wpływają na istniejące filtry i sortowanie?

Answer:
Nie psują ich. W zależności od trybu URL, moduł buduje linki tak, aby filtr działał przewidywalnie na listingu.

Installation and configuration: install the module via Composer, run bin/magento setup:upgrade, deploy static content, and clear cache. In Stores > Configuration enable Kowal Tags Bar, select the dropdown attribute used for tags, choose link mode Magento or Amasty Shopby, configure colors and labels, and verify behavior on category and search result pages. For custom themes enable diagnostic logging to validate tag rendering and URLs.

Version history: initial release with tag bar for a single dropdown attribute, hide empty tag logic scoped to current category and subcategories, Magento default query parameter links and Amasty Shopby SEO URL integration, admin appearance settings for normal and active tags, and diagnostic logging for troubleshooting.
