Your site needs two new pages featuring your latest items. You can do this directly from the Navigation view.
1.
In the Navigation view, select the Stock.html page icon.
2.
Click the New Child Page button () in the Site toolbar. A new, untitled page appears below the Stock.html page. If necessary, use the Site Navigator marquee or the vertical scrollbar to see this new page.
3.
Select Stock.html again and repeat Step 2 to create another untitled page. Notice that both new pages appear on the same level of the hierarchy.
Note
If you add a page where you don't want it, select the page and click the Delete Selected Item button () on the Site toolbar. Then confirm that you want to move the page to the Site Trash folder.
4.
Select the new pages in the site window, and change their names to Acoustic.html and Electric.html in the Inspector.
