Rendering categories in a template with django-mptt

Once you have created categories in your app, you need to display them hierarchically in a template. The easiest way to do this with MPTT trees, as described in the Creating hierarchical categories with django-mptt recipe, is to use the {% recursetree %} template tag from the django-mptt app. We will show you how to do that in this recipe.

Getting ready

Make sure you have the categories and ideas apps. There, your Idea model should have many-to-many relation to the Category model, as per the Creating hierarchical categories with django-mptt recipe. Enter some categories in the database.
