Thanks for getting back to me. No the menu isn’t in a widget. What I was trying to do is to add a secondary menu into the theme functions.php. I thought I would need to add the updated theme file to my childtheme folder but when I was doing that the site went blank. I was able to change the functions.php file and replace the main theme file but I am not sure how that will go during a word press upgrade. that will get overwritten won’t it?
Do I need to have my functions.php page in the child-theme folder if I have made changes to it?
This is what have working now. The footer menu down the bottom is what I was working on
