I have a website with post types that have subtitles for movies. That files are on a specific custom post type using http://www.wpdownloadmanager.com/ pro. Because all custom type posts are movies we have a lot of categories. 744 for now. We have Letter Cattegory including Movie or Series Name and sub categories with Season.
I am wondering if there is an easy way to select categories and sub categories in Backend when a users creates an new post so there is no need to look on a 744 categories to find the movie.
Maybe somekind of filtering or by selecting a main category and filtering child categories ( Movi name ) and after that by filtering sub child categories (Seasons).
Otherwise user needs to seach on 744 Categories to check them.
