Probably, in many online stores you have come across such functionality, when in the product feed you click on the "add to cart" button, you get a pop-up with a cart and at the bottom a block with the name "also bought with this product:", where the products that customers usually order together with the product you clicked on last time are displayed. This module implements such functionality in opencart: it works completely automatically, based on the order database and displays in the cart list (this is shown in the picture) the products that are most often bought with the current product, sorting them by frequency of purchase and displaying the most frequently purchased ones first. Module settings:
1) enabled / disabled
2) display the cart as a pop-up window in the middle of the screen / leave the standard opencart display of the cart near the black button at the top
3) title of the "Also bought" block
4) number of products displayed in the block

Module installation:
The module is easily installed via the ocmod installer, after which you need to update the modifier cache in "Extensions > Modifications". The module settings are in "Extensions > Extensions > Modules > Also buying".

If you want to disable this module, do not forget to also disable the module modifier in "Extensions > Modifications" by clicking on the red minus sign opposite Also buying.
