Create a module. We want to keep a list of supplier contacts in the admin. And we want products to have a supplier attribute with supplier names. The list of suppliers contacts and supplier attribute for a product doesn’t have to be linked. Module name: Supplier. The module should: a. Automatically create a new product attribute (dropdown attribute) called ‘Supplier’ (attribute code: supplier). There needs to be 3 attribute values to that attribute: Supp A, Supp B, Supp C. This attribute & attribute values should be created programmatically and not manually via admin. b. Assign this attribute to the Default attribute set. This should happen programmatically. c. Create a ‘Supplier’ entity (like ‘Customer’ entity), which will contain 3 details: name, email, phone. Ok to use simple textarea input for these. This is not linked to the prdouct attribute. d. Add ‘Supplier’ in the admin left menu, below ‘Customer’, with only 1 sub-menu option called ‘Manage Suppliers’. e. Clicking on the ‘Manage Suppliers’ should take you to a ‘supplier’ entity grid containing the list of suppliers, similar to how you see list of customers when you go to Customers > All customers. f. You should be able to add / delete suppliers from the grid page, like how you can manage customers. g. This supplier list should be made available via GraphQL.
