I want to help solve a configuration: When choosing a manufacturer, show all categories and below the manufacturer's products. For those who surf the web, this is not convenient, because it annoys and exit the website.
 
I want to set that selecting the manufacturer showing the manufacturer's products only.
 
Second: There are manufacturers with 2 or 3 categories and would be excluded.
 
How to solve these 2 items?
 
Thanks in advance
 
=========
 
I googled and found following but this is actually for opencart - but I wish to do same like or better than if somebody can help ... Thanks in advance...
