Keep showing subcategories of main category

Hello everybody,

I’m developing an online shop which needs to keep showing the subcategories from the current main category even if I’m inside the subcategory.

e.g:

[B]- Main 1[/B]

  • Sub 1.1 <-- If I’m in here, it should keep showing itself and Sub 1.2
  • Sub 1.2
    [B]- Main 2[/B]
  • Sub 2.1
  • Sub 2.2
    [B]- Main 3[/B]
  • Sub 3.1
  • Sub 3.2

How can I realize this?
I tried different changes in the[I] /tpl/page/list/list.tpl[/I],
but could not get this ready to work.

Thank you and have a nice day! :slight_smile:
