Q: How to create a collection inside a collection in postman I have tried drag-dropping one request onto another but it doesn't work.
I expected this to work as moving a request from one collection to another can be achieved this way.
Is there a way to achieve this?

A: You can create Folders inside a collection

Select a collection > Click on View more actions > Add folder

This is done mostly to group endpoints with similar functionality/ common initial routes.
Ex: stackoverflow.com/questions, stackoverflow.com/questions/:questionId
You can create more than one folder inside a collection.
