I have a parent category (let’s call it FILMS category-films.php) and it has it’s own template to display all child posts with custom HTML.
Within this category are a number of subcategories (e.g. HORROR, SCI-FI, COMEDY etc.).
I’d like the subcategory pages to display posts using the category-films.php template without having to duplicate it and create a new php file for every subcategory.
I’ve found a few threads online that have functions to achieve this (http://stackoverflow.com/questions/3114934/make-wordpress-subcategories-use-category-template/3117202#3117202) but I’m not sure how this might need to be modified for Roots.
