Featured, Best Seller Product grid is displayed by means of Product Grid/Carousel element http://prntscr.com/k7tjrb
The general tab provides Data source – option to show the displayed product range by:
All products /Sale Products / Products with NEW label /Bestsellers /List of ID
Also, consider using AJAX Product tabs. This element has the same set of option and displays the product grid in tabs.
on the home page, one product grid is shown with title “TOP INTERESTING” and I want to add another carousel with Featured products functionality but after selecting these option products not showing on a home page.
