The main navigation is positioned on the left side of each Merchant Center screen. It contains links to the different applications within a project.
The Merchant Center is composed of multiple independent applications, where each application defines its own set of links. However, the main navigation must contain links from all the available applications for a project. The links are rendered dynamically on runtime, where the main navigation pulls the data from a common source.
Additionally, links to Custom Applications are also fetched dynamically, based on the registered applications within a project.
