Using this plugin you can use WordPress <a href="https://codex.wordpress.org/Conditional_Tags" rel="nofollow ugc">Conditional Tags</a> to enable or disable menu items on the front-end. It works like ‘Widget Logic’ but for menu items.
PLEASE NOTE The conditions are PHP codes that are evaluated using PHP’s “<a href="https://www.php.net/manual/en/function.eval.php" rel="nofollow ugc">eval</a>” function, meaning anyone who has access to the Menu manager in WordPress can execute any code. Be mindful of who has access to the Menu manager.
<h4>Usage</h4>
You must insert conditional tags in the “Visibility” box in the menu item options form. You can use any PHP or WordPress functions to build crazy conditions and logics for menu items. For example, to hide the menu item on homepage you can set the visibility to:
<pre><code>! is_home()
</code></pre>
Show the menu only to logged-in users:
<pre><code>is_user_logged_in()
</code></pre>
Show the menu only to guest visitors:
<pre><code>! is_user_logged_in()
</code></pre>
To show the menu item based on <a href="https://wordpress.org/support/article/roles-and-capabilities/">user capability</a>:
<pre><code>current_user_can( 'manage_options' )
</code></pre>

Menu Item Visibility Control

Control individual menu items' visibility based on your desired condition.

This plugin gives content developers shortcode equivalents to the conditional tags that WordPress provides for theme developments. Each shortcode only includes its contents if a certain condition is true. This allows them to modify what content is shown in any given context on a post-by-post basis. is_page, is_single and is_category allow specific pages, posts, categories to be specified by using the “ids” parameter.
The shortcodes and when they include contents are:
<ul>
<li>is_single – if showing a single post. Use the optional parameter “ids” to specify specific posts.</li>
<li>is_singular – if showing a single post or page.</li>
<li>is_page – if showing a page. Use the optional parameter “ids” to specify specific pages.</li>
<li>is_home – if showing the blog home.</li>
<li>is_front_page – if showing the front page of the site.</li>
<li>is_sticky – if the current post or page is ‘sticky’.</li>
<li>is_category – if showing a category-based archive. Use the optional parameter “ids” to specify specific categories.</li>
<li>is_page – if showing a page.</li>
<li>is_tag – if showing a tag-based archive.</li>
<li>is_tax – if showing a tag- or category-based archive.</li>
<li>is_author – if showing an author-based archive.</li>
<li>is_archive – if showing any archive.</li>
<li>is_year – if showing a yearly archive.</li>
<li>is_month – if showing a monthly archive.</li>
<li>is_day – if showing a daily archive.</li>
<li>is_time – if showing an hourly or shorter archive.</li>
<li>is_feed – if generating a feed.</li>
<li>is_search – if showing search results.</li>
<li>comments_open – if comments are open for the current post or page.</li>
</ul>
Each shortcode also has an “else” shortcode that can go inside it. For example:
<pre><code>[is_single]
This is only shown if showing just this post.
[not_single]
This is shown everywhere else.
[/is_single]
</code></pre>
The is_page, is_category and is_single shortcodes allow you to specify pages, categories, posts on which to show the content if you’d like to only show content within the shortcode on specific pages, posts or categories.
<pre><code>[is_page ids="76, 339"]hello[/is_page]

[is_category ids="5, 7"]hello[/is_page]

[is_single ids="94, 63"]hello[/is_single]
</code></pre>
In general, the “else” shortcode is just replacing “is” with “not”. The one exception is “not_comments_open” as the “else” shortcode for “comments_open”.
Whichever chunk of content is included is processed for shortcodes, so you can use all your other shortcodes and even nest these if you need to.
