Permanently unhide navigation panel in Studio community dropdown

Hi. I'd like to permanently make visible the contents that are displayed when you expand +community.

Is there an easy way to do this? If not, I could change the coding.

Also, I saw on another thread that in order to display navigation for any pages, you must create a new Menu under Appearance > Menus.

What do we call this menu, and will the Studio theme display it automatically, or is there a setting or code we need to change once the menu has been created?

Thanks.
