I'm trying to list all brands in my top menu. Looking at available info using tb/show seems like shop.brands only contains a few brands. What determines which brands are shown here? Is there another for me to get a list of all brands?
The shop.brands variable shows the top 10 brands based on the amount of products in the brand.
A workaround for the navigation is to disable the brand in the theme settings. Then create a new Category Brands and subcategory for each brand you want to show in the navigation.
The navigation items will actually link to the brand pages (and not the categories you just created) due to the way the URL is generated.
Hope this helps!
