[TYPO3-english] ab_linklist - multi parent category

[Dawid Pacholczyk]

Hello group,
  I have a big problem with ab_linklist
I need to create tree like this:

category 1
  - subcategory 1
   - link1
   - link2
  - subcategory 2
   - link3
category 2
  - subcategory 1
   -link4
  - subcategory 2
   - link 5

Now...category 1/2 and all links are diffrent but subcategory 1 and 2
in both categorys are the same. I want to make subcategory with multi
parent category so I can click category 1 subcategory 1 and get
diffrent links when I click cateogry 2 subcategory 1 ( as I
said...subcategory 1 is the same in category 1 and 2)
I wanted to just check all parent categories for my subcategory but I
can check there only one.
How can I do that?

Best regards,
Dawid Pacholczyk
