This is what the instructions say, but the category section does not hide itself, even when I have only one category. Can anyone confirm that this feature works for them? If so, then I am doing something wrong.
How to hide the category selection?
In the admin panel it is possible to include or exclude certain categories, to choose the categories order and to set a default category. If only one category remains, the default category is the same as the only category and creating a new category is disabled, the complete category section hides itself.
