Hi everyone! I'm new to #Odoo18 and currently exploring the interface and modules. I’m using it for a small business. I have a technical background, but not enough to fully understand the Odoo Community code. If you have any tutorials or recommendations, please share them!

Now, let me get to the main topic.

I have users with different roles, and I want to restrict their access to only the necessary sections. For example:

• Manager should see only Sales → Orders (order list and order details) and be able to edit them.
• Accountant should have access only to Invoicing → Customers → Invoices and Invoicing → Vendors → Bills to view and edit invoices.
• Supervisor should have extended rights to manage users and monitor processes, but without access to critical system settings.
• SuperAdmin should have full access to all modules, settings, and permissions management.

Issues I’m facing:

1. Creating users and restricting access

💡 Problem:

When I create a user with User type: Internal User access and no module permissions, they can still see menu items I want to hide. I think this happens because Internal User inherits rights from default groups.

❓ Questions:

1. Can I customize or remove default menu items by modifying the Internal User group?
2. Should I create a new User Type for each role (Manager, Accountant, Supervisor, SuperAdmin)?
   
   

2. Setting up Groups (User Access Rights)

💡 Problems:

1. When creating a custom group, I can select only one module. If a user needs access to multiple modules, I have to create multiple groups and duplicate settings.
2. After adding new Menu items to custom groups, the main menu changed—many duplicates and extra items appeared. Even after deleting the custom groups, the menu did not return to normal.

❓ Questions:

1. How can I set up a group that gives access to multiple modules?
2. Why did my menu get duplicated? How can I remove the extra items and restore the original menu?
