Hi, I’m making this test wizard on codepen.io (javascript + Boostrap)

link: https://codepen.io/marcusparaz/pen/OarwoQ

I would like to make two changes

1)

I would like to make sure that by clicking on the button (MENU CAT 03)
I open the information of (MENU CAT 03)

if I open the button (MENU CAT 05) open info (MENU CAT 05)

without use only the button (avanti)

2)

the button “AVANTI”(At the bottom of the page) should change page
and go to the top of the page.

I would like to ask for your advice.

Sorry, my English is not that good.
