How can I show template dropdown in custom post type?

Question

I have created a new custom post type in wordpress using register_post_type() function But when I click on add new in right side the editor not showing template choose option as you can see in Screenshot_01.png. In Screenshot_2 you can see the default add post option has the template choose option. How can I get that option without using plugin. Here is my exiting code for creating custom post type.

function short_story_type(){
    $labels = array(
        'name' => _x( 'storys', 'Post Type General Name', 'textdomain' ),

Answer 1

Not sure where these screenshots you're talking about have gone, no matter, i think i know the problem.

You simply need to add support for the post type in the templates you want to be able to attach by adjusting the Template Post Type: line for the appropriate template files in your theme.

Example

Template Post Type: post, books, movies

The dropdown should then appear in the editor like it does for posts.

Answer 2

Try to change

'`capability_type' => 'post',`

to

'capability_type' => 'page',
