I needed a thing in Odoo that can allow to create opportunity in CRM through PoS app. But I could not find a ready solution. So I decided to use the app "Sales Order Creation from POS Sales". So I used it and added a "Sales Stage" field to  sales order. And when I want to see all stages Odoo is not showing all the stages because there is no data belonging to that stage. Can someone help me solve this problem without coding. Using studio I also tried to solve it by creating a new model "Sales Stages" but there was no use from it. It would be very nice of you if you could help me with that even if with coding but with a proper direction. Thank you.
