Filter by categories and manufacturers in the OpenCart admin panel

The category and manufacturer filter in the admin panel is a practical improvement to the OpenCart admin panel that makes the product list truly convenient for daily work. It adds quick filters by category and manufacturer to the Catalog → Products section, and displays additional columns (including product ID ) so you can find the items you need faster and spend less time on routine tasks.

Purpose of the module

When a store contains hundreds or thousands of products, standard filters by model, price, and quantity are often insufficient. This module expands the product table in the admin panel: you can filter the list by a specific category or brand (manufacturer) and immediately see the data you need in the columns.

Important: Category and manufacturer filters work via a convenient autocomplete feature —you start typing the name, and the system suggests options and inserts the required ID.
