Sidebar not appearing in htmls


I have generated HTML files of my project. The option selected while generating was ‘Sidebar: With Pages Open’.
Now on clicking generate the sidebar is shown but when I open the saved html file in my system the page opens without the sidebar. Kindly let me know how can we have the sidebar appearing in the system file as well.
This is a bit urgent so expecting a quick response

When opening the generated HTML make sure you’re opening the main start.html page. The sidebar is actually part of that page and the subsequent pages are opened in an iframe on the same page as the side bar. So if you’re opening each individual page’s HTML file directly there won’t be any sidebar.
