Thanks a lot for posting this issue!
Unfortunately, I’m afraid it would not be possible to support you for this customization. Our theme does not support your request yet at the moment.

I have the same question, I only need to fetch “15 Must Read Articles” from a category, I have created a category called “mustread”, can you tell me how to changing functions.php to achieve the object?

Thank you!

To solve this issue, please open the functions.php file /go to line 799 -> 804.
Replace the following codes:

 $post_array = array(
'posts_per_page' => $max_number_posts,
'order' => 'DESC',
'post_status' => 'publish',
'ignore_sticky_posts' => 1
);

With new codes:

$post_array = array(
'posts_per_page' => $max_number_posts,
'order' => 'DESC',
'post_status' => 'publish',
'ignore_sticky_posts' => 1
);
$post_array['category__in'] = array( /*categories ids ex: 1, 2, 3*/);

See the Screenshot below:

Please change your categories ID here: /*categories ids ex: 1, 2, 3*/
If you want to know Id of the categories, you can hover on the categories.
