How can a hierarchical menu be made dynamically in PyroCMS?

I am using PyroCMS Version 1.1.0. It has the navigation module that is used to show up menus in front end. But I couldn't find the way out to generate hierarchical menus like I am working on category module. And in this, I have to generate a menu Category under which开发者_StackOverflow社区 I have to show up multi-level menus for categories and subcategories.

Please help me with this.

Each link can have a "parent". Just go to the Navigation page and do it.

This does not support Page Children and the interface is not as awesome as it could be, but those changes are coming in 1.2.
