Can we adjust the number of recommendations displayed within the page width?

Yes, we can adjust the number of products displayed from the Visual preferences section.

In the Product settings, you will find the Width attribute that allows you to adjust the number of products that will be displayed within the slider area.

In case you want to display more products, just reduce the pixel value  of the product boxes. Otherwise, if you want to display fewer products, set a higher value for the width attribute.

It's important to note that the fit of the product images may be affected when the product width is changed. If so, please take a look at the related article on how to scale the product image so that it is fully visible
