Description
This plugin helps you add jQuery and Javascript code snippets only on specific pages and posts.
It works with all types of custom post types as well. Each script added to a page or post, will run only on that specific post.
Scripts can be added in a meta box when editing a page.
This plugin uses the wp_head() action hook, and adds the code to the header of the page.
Most of the themes using this hook, so it works on most of the themes.
Tested & works with Gutenberg.
