This module allows adding related products to buybox

Installation

Admin settings

There are no admin general settings. The module is enabled by default when installed.

To have related products displayed in the buybox feature has to be enabled for each product separately on the product page in the admin panel (it’s disabled by default)

Open

Backend

Frontend

By default, related products are displayed under the buybox form as a list with Related product tile and add to cart checkboxes.

Open

Using this form user can add selected products to the cart (possibly all of them) along with the main product with one click.

A bunch of settings can be added and adjusted via xml (catalog_product_view.xml)e.g headline, subheadline, items limit, and add to cart button/checkbox.

Possible adjustments (they require additional work - not given by default in this module): display this section as a products carousel.
