Only show child category on this category parent page

Hi !

I want to know if this plugin is good for :

I have some catagories and sub categories..

For example :

CAT A (VGENE_FR)
– SUB A1 (LIVES)
– SUB A2 (OTHERS)

CAT B (VLUVITY_FR)
– SUB B1 (LIVES)
– SUB B2 (BEFORE CRAVITY)

I want to had on my sidebar ONLY the current category..
So CAT A don’t show CAT B…
