For the Custom Post type Categories, First you need to register the Custom Taxonomies then you have to print/render the those each array of custom taxonomies rendered by wp_get_post_terms( post ID, Taxomony Name );

Thanks

Before using Taxonomies first you have to register the Taxonomies(tags, Categories etc) using your custom post type register name. Then you can replace the function to show respective custom taxonomies on Theme Directory/ template-parts/ content.php file. Then to show the custom taxonomy list you can make the copy of archive.php file and rename the file as taxonomy-(your registered taxonomy name).php.

You can find many tutorials on internet/youtube about registering Taxonomies and related stuff. You can follow them for help

Thanks

Ok for widgets you have to add your registered Custom Post Type on query codes. On Theme Directory/inc/newscard-widgets.php file, you can find the below code on line no: 195, 361 and 483.

'post_type' => array('post'),

to the mentioned code you have to add the registered Custom Post type as

'post_type' => array('post', 'your-custom-post-type'),

and to add taxomony (custom category) on dropdown list you have to add the taxomony on dropdown query code. you can find below code on line no: 169 and 335.

'selected' => $instance['category']

add the the taxonomy query code just beneath the mentioned code followed by comma (,) and after adding the code should look like this.

'selected' => $instance['category'],
'taxonomy' => 'your-custom-taxonomy'

We haven’t tried instantly but hope it should work and if it doesn’t work you for you then i think you have to hire a developer who is more familiar with the codes and can customized the Theme code for you.

Thanks
