I’ve been unable to find a way to reference Image Primary through dynamic content. I’ve been unable to locate any of these additional fields, only native WP menu fields.
I was hoping you could help me complete my looper and provide me the key?
In post meta, this is stored as menu-item-anchor_graphic_image_src. In your looper you can use looper.item.ID as your argument to the post.meta dynamic content. Let us know if that helps and have a great day.
