several layered problems...

[PF22]

Hi there.

I have several problems with my layerd version since I updated my prestashop from 1.4.3 to 1.6.1.5.

For exemple I have a long list of sub-categories to chose in my layered block, so first when I check one sub-catégory I woudl like to go back to top of the page automatically.

 

Then, when I make a selection in layered block I got a product list and when I go to one product page, when I click on previous page button on my browser I lost the layered selection...

 

I am using layered block V 2.1.3.

 

Thnaks for any help.
