As posted on Pages come to Blogger In Draft, Go to Posting > Edit Pages tab and click New Page.
After making your desired static page and after publishing the page, you can link to it from the new Pages widget.
This blogger widget lets you add links to your pages as navigation bar at the top of your blog, or in your blog's sidebar.
In the Pages blogger widget, you can decide which pages will have links and the order that they will appear. By checking the "Add new Pages by default" box, you can also choose whether you want the links to be automatically created for static pages whenever you create them.
