    Hi,
    I have the following hirarchy:
    Category 1
    Category 1.1
    Category 1.2
    Category 2
    Category 2.1
    Category 2.2
    What’s the method to get all of the subcategories of category 1 (e.g. Category 1.1 and Category 1.2) when I know the post ID (outside the loop).
    Thanks 🙂

    P.S.
    I figured it’s supposed to be something with wp_get_post_categories, but I couldn’t find any reference to using the args for such a thing.
