Need Help

I have created 3-4 docs just like this – https://betterdocs.co/docs/wordpress/ and now for example if I go to “Learning” – https://betterdocs.co/docs/wordpress/learning/

then I am able to see all docs like – Getting Started, Learning, Configurations and FAQ but I dont want like this and I only need learning alone when I click and go to this page – https://betterdocs.co/docs/wordpress/learning/

Is there any option to do that as I am not able to find and I am a WordPress developer only and if you show me a filter or anything then I will implement it
