I work with SupaDupa as an e-commerce platform, which recently introduced sub-menus as a site upgrade. A few of the other sellers I know have been working to add sub-menus to their sites and asked me to take a look at it and see if I could add some screenshots for the process.
I'm going to go over my general process for how I did everything. For simplicity, I'm using SD as an abbreviation for SupaDupa throughout this page.
