Add <a href="https://codex.wordpress.org/Navigation_Menus" rel="nofollow ugc">Navigation Menus</a> to <a href="https://wordpress.org/extend/plugins/advanced-custom-fields/" rel="ugc">Advanced Custom Fields</a> (ACF) with the Nav Menu Field plugin! This plugin adds the Nav Menu Field type to ACF (version 5 & 4), allowing you to select from the menus you create in the WordPress Admin backend to use on your website’s frontend.
Using ACF, you can set the Nav Menu Field to return the selected menu’s:
<ul>
<li>ID for lightweight coding,</li>
<li>Object for more involved programming, or</li>
<li>HTML (generated from <a href="https://codex.wordpress.org/Function_Reference/wp_nav_menu" rel="nofollow ugc">wp_nav_menu</a>) for quickly displaying a menu.</li>
</ul>
I created this plugin because I needed to display a secondary menu that changed depending on what page you’re on. Most of those pages were children of the same page, but then I had to throw a couple of Custom Post Types in there too. Because of the Custom Post Types, I couldn’t just grab the top most parent for the current page and use <a href="https://codex.wordpress.org/Function_Reference/wp_list_pages" rel="nofollow ugc">wp_list_pages</a>. So I did some research and decided to extend the functionality of my favourite plugin, <a href="https://wordpress.org/extend/plugins/advanced-custom-fields/" rel="ugc">Advanced Custom Fields</a>. Now when I create a new Page or Custom Post, I just select the menu from a drop down menu!

Advanced Custom Fields: Nav Menu Field

Does what it says

This plugin might be old, but it still works perfectly and does exactly what I needed. No PHP errors, warnings, or notices, either. Running with ACF PRO 5.6.7 and WordPress 4.9.1.

Oldie but Goodie

Let's don't make any mistakes here - this addon is perfect and needs no changes, that's why there is nothing to update here.

Used it in many sites. Thank you!
