Hello,
8. Change Icons elements http://prntscr.com/j7op82 to List icon with List icon items inside http://prntscr.com/j7opnh or something else.
1. Go to edit page > Page Layout > Sidebar Position > Without.
2. I’ve changed Breadcrumbs Style for the page from Default to Width Background http://prntscr.com/j7ovqo
