I am trying to list posts from different categories with the "latest posts" widget. When customizing the shortcode;
"Posts from which categories do you want to show? Enter a comma separated string with category ids here. Leave empty if you want to display posts from all categories. Example: 1,5,12"
option is available. However i need,
"posts from intersections of different categories. Example 1+5+12"
Displaying posts that belong to all of those categories.
Can you help
