I have pages attached to categories with sub-categories.
In the “Include or Exclude results with specific tags, categories and taxonomy terms” tab, when I INCLUDE a category I expect its subcategories to be included.
This works up to a point, all the pages in the categories and sub-categories are returned in the Results page.
However, the drop-down interface does not work as expected in screenshot (a). I would like it to display my sub-categories as well as in screenshot (b)
I found that the only way to get them displayed is to INCLUDE all the sub-categories one by one. This can be tiresome when there are a lot of them!
If this works as intended by the plugin author, I suggest adding a setting to enable the display of sub-categories in the drop-down interface.
