What is the best way to store nested categories with multi-level nesting in MongoDB?

Question

MongoDB

Once upon a time, when I was working with the LAMP stack, I made a table in Mysql where I wrote down IDs in the category of her children. And there was a field to indicate that the category is the root (entrance to the recursion). And recursion brought it all out .
With such an idea, mongoDB was laughed at. What's the best way to do this in Mongo... Do nested arrays in one record ? But I have no idea how to make requests later ... it seems that it is possible to work adequately only with two-level nesting
