This plugin enables a Custom Menu to “include” any other Custom Menu, so groups of items that get repeated across multiple menus can be defined just once and then included into any other menu at will.
If you have a set of menu items that you repeat across several menus, it can be a bit of a pain when 
one of that set needs updating and you have to go through all your menus changing each one.
This plugin allows you to define the subset of items as a separate menu, and then include that menu 
into any other menu. If you then need to maintain one of the items in the subset, you only need to update 
one menu, and the change automatically gets reflected in all the other menus that include that subset!
It’s as easy to use as adding a Post, Page, Category or Tag to your menu…
With the plugin activated, go to your Menus page in admin. 
As well as being able to add Posts, Categories, etc, to your menu, you should now see a metabox for 
Navigation Menus which has checkboxes for each of your defined Menus (if you don’t see the metabox, 
check your Screen Options settings at the top of the page). 
All you need to do is create your submenu (as you would any other menu), 
open the menu you want to insert the new submenu into, 
select the submenu from the Navigation Menus metabox, 
Add it, 
and position it. 
Save and you’re done!
The inserted Menu replaces the Navigation Menu item in the menu. You can insert multiple instances of the 
same submenu into one menu, and you can include a submenu into as many other menus as you need.
<h4>Perpetual Loops</h4>
The one thing that the plugin guards against is getting into a never-ending loop : it won’t prevent you 
setting one up (see FAQs as to why), but it will not output any submenu that has itself as an antecedent.
For example, you can set up menus such that Menu A includes Menu B, which includes Menu C. Fine, no problem. 
However, if you were to also add Menu B into Menu C as a Navigation Menu item, 
then no matter which menu you choose to output, you have a potential loop 
(… B, includes C, includes B, includes C, … and so on).
If WP_DEBUG is enabled, the plugin will print a warning wherever it has taken action to prevent a loop condition. 
This behaviour can be changed by hooking into a filter (see FAQs).
<h4>Frontend Only</h4>
The plugin only performs the menu replacement at the frontend of WordPress (ie. not on Admin pages). 
This behaviour can be changed by hooking into a filter (see FAQs), 
but please ensure that you do not enable it for the Menus admin page!

This is so useful and I was surprised that this didn't already exist in core. Thanks for building it!

Awesome! Should be in core WordPress

With this plugin you can easily add a dynamic login/logout menu item to any menu on your WordPress site. The menu item will change based on whether the current user is logged in or logged out. You can also set a specific login page url, login redirect url and a logout redirect url.
Thanks to Juliobox for his prior efforts on the BAW Login/Logout Menu plugin which this is derived from
<h3>CONFIGURE SETTINGS</h3>
After installing and activating the plugin, you can find the settings in your dashboard under: <code>Settings > Login or Logout</code>
Login Page URL – This should be the URL to the page where your users will login at. For most wordpress sites this will be <code>/wp-login.php</code> but if you’re using a membership plugin like MemberPress, it might be something like <code>/login/</code> instead.
Login Redirect URL – This is the URL you would like your users to be redirected to after they’ve successfully logged in. You can set it to <code>/</code> to take them to the home page after logging in. If you’re using a membership plugin like MemberPress, you might want to use <code>/account/</code> instead. NOTE: Some plugins may override this if they are configured to redirect your users somewhere else during login.
Logout Redirect URL – This is the URL you would like your users to be redirected to after they click the Logout link from this menu item. Use a <code>/</code> to redirect them to the home page, or you might want to redirect them back to the login page at <code>/login/</code> or <code>/wp-login.php</code> etc.
<h3>ADD ITEM TO MENU</h3>
In your dashboard visit <code>Appearance > Menus</code>.
Then at the top right of that page click the <code>Screen Options</code> button and ensure that <code>Login/Logout</code> checkbox is checked.
Then select a menu to edit, or create a new menu if you don’t already have one.
In the left sidebar find <code>Login/Logout</code> and click the checkbox next to <code>Login|Logout</code> and then click <code>Add to Menu</code>.
You can now drag the menu item wherever you’d like it to appear in your menu. The <code>URL</code> in the menu settings must be left at <code>#lolmiloginout#</code> but you can change the <code>Navigation Label</code> if you’d like it to say something else. Just ensure that the <code>|</code> is there in the label separating the two words.
Now save your menu. That’s it!
<h3>BLOCK EDITOR (NAVIGATION BLOCK)</h3>
If you’re using the block editor’s Navigation block:
<ol>
<li>Add or edit a Navigation block on your page or in the Site Editor</li>
<li>Click the (+) to add a new link</li>
<li>In the search field, type “login” or “logout”</li>
<li>Select “Login|Logout” from the suggestions</li>
<li>The link will automatically show “Login” to logged-out users and “Logout” to logged-in users</li>
</ol>
You can also manually type <code>#lolmiloginout#</code> as the URL if you prefer.
<h3>Troubleshooting</h3>
After logging in, menu still shows “Login” or Vice-Versa – This is most commonly caused by caching. If you’re using a caching solution such as Cloudflare, WPRocket, or others, be sure that caching is disabled for logged in users, and disable browser caching options as well.
Login is redirecting users somewhere other than my settings – Many times other plugins will have their own login redirect handling which overrides this plugin’s, such as MemberPress for example. In this case, the other plugins will need to be configured to redirect the user where you’d like them to go.

Add a dynamic "Login" or "Logout" menu item to any WordPress Menu and control redirects.
