[TYPO3-dam] dam_frontend : show category tree till level 2

[Tizian Schmidlin]

Hi folks,

I've got a little problem with the categorytree of dam_frontend and I 
hope someone may help me with it.

What I'd like to have is the following:

Categorylist :
Cat 1
  -- Cat 1 1
  -- Cat 1 2
Cat 2
  -- Cat 2 1
  -- Cat 2 2
  -- Cat 2 3
   -- Cat 2 3 1
   -- Cat 2 3 2
  -- Cat 2 4
Cat 3

...

I'd like to have a Categorytree looking like this:

Cat (v) 1
  -- Cat 1 1
  -- Cat 1 2
Cat (v) 2
  -- Cat 2 1
  -- Cat 2 2
  -- (v) Cat 2 3
  -- Cat 2 4
Cat 3

The (v) is the open/close button of the category tree.

So you see, I'd like to have a category tree which is by default opened 
till the second level.

Has anyone an idea how to configure this?
