Easily Embed Dynamic Lazy Loading Youtube Videos And More Simply By Pasting The Url.
This plugin does most of the work client side, and waits for the page to finish loading so embeds do not slow down your site. 
Shortcodes are not needed (but are available), just add a clickable link to the youtube video, and the plugin will find all the youtube.com and youtu.be links, and replace them with an embed.
You know how sites like discord let you paste a youtube url, and an embed of the video shows up? 
This plugin works kind of like that, while also working with playlists, live streams, channels, youtube search, etc.
YouTube has an organized url system, and this plugin recognizes it. 
Every youtube playlist id starts with “PL”, and youtube uses many other consistent url methods like this.
Now supports local pdf embeds. 
Now supports google doc to pdf embeds.

The default custom menu in WordPress only allows adding a link that leads to a list of posts and pages belonging to a taxonomy (category, tag, etc). If you want to list the posts and pages themselves and if you want WordPress to do this automatically for you, then I hope you will find this plugin useful.
Also works for custom taxonomies and custom post types 
NEW: CPCM V3 now provides support for Full Site Editing with the Gutenberg Block Editor 
WARNING: Coming from version 1.x? There are breaking changes, read the changelog before upgrading.
<h4>Using it</h4>
Enable the plugin and go to either Appearance > Menus or Appearance > Customize or Appearance > Editor. Add a category (or other taxonomy like tag or custom) to the menu. Next, you can choose if you would like to replace the category by the posts or pages themselves.
For each Category in your menu, you now have the following extra configuration options:
<ul>
<li>Replace by posts in the category y/n; </li>
<li>specify the (maximum) number of posts you want to show for this item (max 10);</li>
<li>their ordering ascending or descending by Title, Date or Menu Order;</li>
<li>specify the title for the menu items. For this you can use %post_title, %post_author and other wildcards, see ‘Other Notes > Wildcards’. Default value: %post_title</li>
</ul>
<h4>Wildcards</h4>
You can control the title of the menu items generated by the plug-in with the following wildcards:
<ul>
<li>%post_title</li>
<li>%post_author</li>
<li>%post_date for the unformatted post date: 2012-11-10 18:14:23</li>
<li>%post_date() for a formatted post date with the following default formatting: November 10th, 2012</li>
<li>%post_date(<your formatting here>) for custom date formatting. Example: %post_date(l jS \of F Y, h:i:s A). See <a href="https://codex.wordpress.org/Formatting_Date_and_Time" rel="nofollow ugc">https://codex.wordpress.org/Formatting_Date_and_Time</a> for formatting options.</li>
<li>%post_date_gmt</li>
<li>%post_date_gmt()</li>
<li>%post_date_gmt(<your formatting here>)</li>
</ul>
