(Apologies if I am not using the exact English terms; I'm using SharePoint in French.)
I'm using SharePoint online. When I edit the home page of the site, a ribbon appears giving me many possibilities, including adding web parts and applications, and setting the layout. This would allow me, for example, to add a given view of a list to that page.
Currently, if I create another Page, it is displayed in the new (Modern) view. If I try to edit it, no ribbon appears and I'm limited to added about a dozen things, which do not include the possibility of adding a view of an existing list, or any existing webpart. Furthermore, I cannot change the layout of the page, by having multiple columns.
Unlike other "pages" of the site, there is no link on a created Page which allows me to switch to a classical view.
How can I either switch a Page to the classical view and have access to the ribbon when editing OR, at the very least, how can I add existing lists on that page?
