Hey @waynepatt58,
This site (https://xthemetips.com/breadcrumbs-for-x-pro-header-builder/949/) is a single post so replicating that, you really would be limited to three areas (1st section with the fullwidth image and 2nd section containing the content and sidebar). You will need to put all your page’s content in the 2nd section - 1st column and that would be it. You must not add anymore rows.
Maybe your problem is adding rows to the 1st column? In that case, it’s not possible. You will need to use the Global Block feature to build your content. Or, you will need to use the Post and not the Page post type like your sample site and then do the same modification they had. They have modified the single post template to display the featured image above the content and sidebar. You will need to contact the site owner if they can do the same for your site.
In terms of replicating the layout of your sample page, it’s already achieved. Your test page already replicates the setup of your sample page.
Thanks.
