I am trying to display a widget on a category archive page, its category children and the post page associated with the category or children.
Currently I am able to accomplish this but whenever I add a new child category I have to go in and select the child category.
I see the option to exclude from displaying on a certain category / child categories, but not the reverse option to only show on a certain category and its children. Is this possible?
This would be helpful when adding new child categories so that I don't need to go in and add the widget to the new child category.
