To identify your top-performing products per category, navigate to the "Location" dashboard.
Choose your desired date range and store location from the top filters.
After applying your filters, scroll down to the "Top Products" table. First, click on the "Category" header to sort by category (much like how you would sort an Excel document). And then holding down "Shift," click on the "Total Revenue" header.
You'll then be able to easily sift through your top-performing products by category AND total revenue contribution!
