1. Navigate to Admin > Media Settings > Categories.
2. Enter a Category Name.
3. Click Create.
4. Click the Add Child button next to a Category Name to add a subcategory to the category.
5. Keep in mind each category and subcategory name must be unique within each category hierarchy.
Tip: Click a Category Name to edit a previously saved category. You may click and drag subcategories to arrange them under parent categories. They are automatically saved in their new position alphabetically.
