This could be done as follows: - [ ] Create a model with Many-One relationship to `NavbarEntry`. (refer [ForeignKey](https://docs.djangoproject.com/en/1.10/topics/db/examples/many_to_one/) attribute) - [ ] Use the nested set inside `navbar.html` with a simple [bootstrap dropdown component](https://v4-alpha.getbootstrap.com/components/dropdowns/). - [ ] Add validation to nested child URLs.
