I appreciate your help. I have added all my products to the website and have included the brand of each item as an attribute. I want the user to be able to browse by brand like they can do with category in the header/main menu? How do I add a list of brands in the header?
Sorry but there is no option in Theme Settings for that.
You can try creating an HTML block and add the brands to it using the Extra menu list element and then assign links to the brand according to your needs.
If you are trying to ask anything else then provide with some relevant screenshots of the specific area to check it myself and help you out accordingly.
