Installation

The addon is installed via the standard CS-Cart interface: Add-ons → Manage add-ons. Find "Product sorting by features" and click "Install".

Configuration

After installation, open the addon card and configure:

• Pre-sort by availability — when enabled, in-stock products will be displayed first for any selected sorting.

To add features to the sorting list, go to Catalog → Product features. For the desired feature, enable "MS: Use for sorting". For numeric features (volume, weight, etc.), enable "MS: Sort as numbers" for correct sorting.

Using the addon

On the storefront, in a product category, the sorting block will show additional options — by product code and by each enabled feature. The customer can select the desired option from the dropdown.

Sorting names can be changed in Administration → Languages → Translations. Look for keys: sort_by_code_asc, sort_by_code_desc, sort_by_ms_sorting_by_features_(feature_code)_asc, sort_by_ms_sorting_by_features_(feature_code)_desc. For Ultimate theme — with prefix abt__ut2..

Verification

Open a category on the storefront, select sorting by feature — products should reorder. Check numeric sorting on features with numbers.

Maintenance

Update — via Upgrade Center or manually from the addon repository. Uninstall — via Add-ons → Manage add-ons.
