Hi Ron,
Sorry for the late reply as your topic was in spam and I just recognized it.
About the featured content in the High Responsive Pro theme and other customizer-based themes:
1. Go to “Appearance => Customize => Theme Options => Featured Content”.
2. Then you need to determine the type you want to display Post or Page or Posts for a particular category or tag. So, select the “TYPE”
3. After you select the type, it will display the settings accordingly.
* If you select type as “Post”, it will allow you to select the particular post
* If you select type as “Page”, it will allow you to select the particular page
* If you select type as “Category”, it will allow you to select the category
* If you select type as “Tag”, it will allow you to select the tag
4. Here you can also select other settings like the number of content, display content, display meta, columns, title and so on.
5. After making changes, finally click on the “Publish” button.
