Add additional content on a post per post basis in the edit or publish post screen. The additional content editor can be used with all public post types.
Use this plugin for content that you, for whatever reason, don’t want to be included in the post content itself, like <a href="https://keesiemeijer.wordpress.com/2015/05/25/how-to-remove-specific-shortcodes-from-post-content/" rel="nofollow ugc">shortcodes</a>, or code snippets used by other plugins.
Another benefit of using this plugin is if you want content to be displayed before or after content that is automatically added by other plugins. The <a href="https://wordpress.org/plugins/additional-content/faq/" rel="ugc">priority parameter</a> will let you do just that.

Note: This plugin does not support the block editor but should continue to work without issue when using it with custom post types and the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor Plugin</a>.
Before WordPress displays a post’s content, the content gets passed through multiple filters to ensure that it safely appears how you enter it within the editor.
One of these filters is <a href="https://codex.wordpress.org/Function_Reference/wpautop" title="wpautop" rel="nofollow ugc">wpautop</a>, which replaces double line breaks with <code></code> tags, and single line breaks with <code> </code> tags. However, this filter sometimes causes issues when you are inputting a lot of HTML markup in the post editor.
This plugin displays a checkbox in the publish meta box of the post edit screen that disables the <a href="https://codex.wordpress.org/Function_Reference/wpautop" title="wpautop" rel="nofollow ugc">wpautop</a> filter for that post.
Also adds a ‘wpautop’, or ‘no-wpautop’ class to the post_class filter to help with CSS styling.

Toggle wpautop

Easily disable the default wpautop filter on a post by post basis.
