#vallo29 – sorry I dont know Italian so you will have to put up with my Aussie English 🙂
I am not sure how to answer your first question, I would have to play around to see if I can get it to work.
but I can answer your second question eg put the list of the items at the top right in in a single line (now it’s in two).
This is done under Appearance > Menus, on the right hand side you can drag the menu items around. to have your 2 items “walk” & “copertine” in 1 line under “Collaborazioni” if you drag “copertine” to be a sub item of “walk” there will appear in one line. if both are going to have the circles you mentioned (not sure how to do this yet) both should point to the one page link.
I hope my English has not confused you, and I hope I have help a little.
