Creatus theme options are separated in to corresponding options files and are located in
creatus/inc/thzframework/options folder. Each of these files can be changed or extended.
If theme options set file is located in Creatus framework theme options folder, the Creatus child theme is able to override the options set files by copying the file in to creatus-child theme corresponding folder;
├─creatus/ │ ├─inc/ │ └──thzframework/ │ └─theme/ │ └─options/ │ ├─posts/ │ └──post_media.php │ └─creatus-child/ ├─inc/ └──thzframework/ └─theme/ └─options/ ├─posts/ └──post_media.php
Once you copy the file over you can make desired changes to theme option file and extend your creatus-child theme options.
