Andrea

P.s.: I also formulate a different question: 

I'd like that, after clicking on the triangle, would be shown the articles in the subsection. I attach a quick example: 

The page in question:

https://support.magicstore.cloud/hc/it/categories/115000039291-MagicStore

It doesn't work to me. When I click to "See all articles", nothing happens. 

Is it because I got a different chunk of code to show the articles? Instead, this chunk of code in question shows articles in a new tab. 

My support:

https://support.magicstore.cloud/hc/it/

And category page which I'm talking about:

https://support.magicstore.cloud/hc/it/categories/115000039291-MagicStore

Can you give it an eye or help me in any other way please? 

Thank you.
