Nicemenu and slicedmenu

Hello,

Happy new year,

One question, I've nicemenu and slicedmenu modules on my website.
My nicemenu can get one or 2 levels.

On a view page of listing of articles (level 2), I've got :
- in nice menu the first level selected,
- one block with slicedmenu whose appear with the levels 2 of the same menu of level 1.

But, when I arrived on the details of my article (one article of my view list), my nicemenu have no selection of level 1, and the slicedmenu block is invisible.

I think it's easy to add a var in my template page to indicate where in the nicemenu I am in level 2, but I don't know how ?

Can you help me please.

Thanks.
