Ursa Major Solar would like the navigation menu in the customer portal to be vertical.

Two options that make it possible to have a vertical navigation menu in the customer portal are B and D. A navigation menu is a component that allows users to navigate through different pages and sections of your Experience Cloud site. By default, the navigation menu is horizontal, but you can change it to vertical by using different options. One option is to download an app from AppExchange, which is a marketplace where you can find and install apps, components, and solutions for your Experience Cloud site. Another option is to write custom code, which allows you to create your own custom components and layouts for your Experience Cloud site.
