I'm trying to create my own custom module for the products category with a hierarchical view.

My main requirement that i'll be able to create a view with folds , unfold capability. Here's an example:

|Category Root (UNFolded)

     |Category A  (UNFolded)

             |Sub Category A1

     |Category B (UnFolded)

             |Sub Category B1

             |Sub Category B2

             |Sub Category B3

     |Category C (Folded)

-----------------------------

If i click on category C Row I ll be Able to unfold it and see it's sub category.

My first Attempt

class odepoCategory(models.Model):

_name = 'odepo.category'

nomCategory = fields.Char(string='Nom Category')

parentCategory = fields.Many2one('odepo.category', string='Super Category')

subCategories = fields.One2many('odepo.category', 'parentCategory', string='Sous Categories')

Howerver i don't have a clue on how to show the hierarchical view.
