Create dashboard setting which lets me set ID of category which is inserted into template

Question

Part of a function i'm using in my single.php page is

$myposts = get_posts(array('numberposts' => 10, 'offset' => 0,'post_status'=>'publish','category' => 32));

I need to make the number 32 dynamic so it can be set from the dashboard

I'm familiar with advanced custom fields for posts. Is there a similar plugin that would let me create custom options? Or can someone suggest a good modern tutorial on creating a basic option like this in the dashboard

Thanks

Answer 1

I found this plugin that let me create custom options and set the value dynamically in my templates. Worked out fine
