I'm using Drupal-8.0.1. And I have been developing one custom module. In that module, I have created a custom form that to be shown in the path admin/config/people/ban/settings.
By default when we enable Ban module we will found IP address ban menu link under admin/config/ path, when we click on the IP address ban link it goes to admin/config/people/ban.
I want to create a menu tab inside the admin/config/people/ban as Default and Settings.
In Default Menu tab I want to show the default content in the path admin/config/people/ban on the other side Settings menu tab I want to show my custom module form.
How can I do this in my module?
