So I think that this is probably a very simple thing that I am just not getting. Added a child page to the menu titled “backgrounders”, which is set as a parent page, but what I set as the child page doesn’t show up as a child page if I want to get to it by clicking on the parent page on the left hand menu bar. How do I get the child page to show up under the parent page?
to show the child menu item slightly aside and below the parent menu item, you would need to use a custom menu. Here is a support post explaining WordPress custom menus: https://en.support.wordpress.com/menus/
This way you can also adjust your menu in more detail, adding categories and other links and deleting the default “Home” link, if you like to.
