Il sistema di menu di WordPress ha una caratteristica integrata che permette di aggiungere descrizioni alle voci di menu. Tuttavia, questa caratteristica è nascosta in modo predefinito. Anche se abilitata, la visualizzazione non è supportata senza l’aggiunta di codice. La maggior parte dei temi non è stata progettata tenendo conto delle descrizioni delle voci di menu. In questo articolo vi mostreremo come abilitare le descrizioni dei menu in WordPress e come aggiungere descrizioni nei temi di WordPress.
Nota: per questo tutorial è necessaria una discreta conoscenza di HTML, CSS e dello sviluppo di temi per WordPress.
Quando e perché aggiungere le descrizioni dei menu?
Alcuni utenti pensano che l’aggiunta di descrizioni ai menu sia utile per la SEO. Tuttavia, riteniamo che il motivo principale per cui si desidera utilizzarle sia quello di offrire una migliore esperienza utente sul proprio sito.
Le descrizioni possono essere utilizzate per dire ai visitatori cosa troveranno facendo clic su una voce di menu. Una descrizione intrigante attirerà più utenti a fare clic sui menu.
Passo 1: Attivare le descrizioni dei menu
Andare su Aspetto ” Menu. Fate clic sul pulsante Opzioni schermo in alto a destra della pagina. Selezionate la casella Descrizioni.
In questo modo si abilita il campo delle descrizioni nelle voci di menu. In questo modo:
Ora potete aggiungere descrizioni alle voci di menu del vostro menu WordPress. Tuttavia, queste descrizioni non appariranno ancora nei temi. Per visualizzare le descrizioni dei menu, dovremo aggiungere del codice.
Passo 2: Aggiungere la classe walker:
La classe Walker estende la classe esistente in WordPress. In pratica, aggiunge una riga di codice per visualizzare le descrizioni delle voci di menu. Aggiungete questo codice nel file functions.php del tema.
class Menu_With_Description extends Walker_Nav_Menu {
function start_el(&$output, $item, $depth, $args) {
global $wp_query;
$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
$class_names = $value = '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
$class_names = ' class="' . esc_attr( $class_names ) . '"';
$output .= $indent . '<li id="menu-item-'. $item->ID . '"' . $value . $class_names .'>';
$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr( $item->attr_title ) .'"' : '';
$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr( $item->target ) .'"' : '';
$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr( $item->xfn ) .'"' : '';
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
$item_output = $args->before;
$item_output .= '<a'. $attributes .'>';
$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
$item_output .= '<br /><span class="sub">' . $item->description . '</span>';
$item_output .= '</a>';
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
}
}
Passo 3. Abilitare Walker nel wp_nav_menu
I temi di WordPress utilizzano la funzione wp_nav_menu() per visualizzare i menu. Abbiamo anche pubblicato un tutorial per i principianti su come aggiungere menu di navigazione personalizzati nei temi WordPress. La maggior parte dei temi WordPress aggiunge i menu nel template header.php. Tuttavia, è possibile che il tema abbia utilizzato qualche altro template per visualizzare i menu.
Quello che dobbiamo fare ora è trovare la funzione wp_nav_menu() nel tema (molto probabilmente in header.php) e cambiarla in questo modo.
<?php $walker = new Menu_With_Description; ?> <?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu_class' => 'nav-menu', 'walker' => $walker ) ); ?>
Nella prima riga impostiamo $walker per utilizzare la classe walker che abbiamo definito in precedenza in functions.php. Nella seconda riga di codice, l’unico argomento aggiuntivo che dobbiamo aggiungere agli argomenti esistenti di wp_nav_menu è 'walker' => $walker.
Passo 4. Stilizzare le descrizioni
La classe walker aggiunta in precedenza visualizza le descrizioni degli elementi in questa riga di codice:
$item_output .= '<br /><span class="sub">' . $item->description . '</span>';
Il codice precedente aggiunge un’interruzione di riga alla voce di menu aggiungendo un tag
<li id="menu-item-99" class="menu-item menu-item-type-post_type menu-item-object-page"><a href="http://www.example.com/about/">About<br /><span class="sub">Chi siamo?</span></a></li>
Per modificare l’aspetto delle descrizioni sul sito, è possibile aggiungere del CSS nel foglio di stile del tema. Abbiamo effettuato dei test su Twenty Twelve e abbiamo utilizzato questo CSS.
.menu-item {
border-left: 1px solid #ccc;
}
span.sub {
font-style:italic;
font-size:small;
}
Ci auguriamo che questo articolo vi sia utile e che vi aiuti a creare menu dall’aspetto gradevole con descrizioni di menu nel vostro tema. Domande? Lasciatele nei commenti qui sotto.

In PHP 8.0 and higher this with throw a critical error.
You need to find this line:
function start_el( $output, $item, $depth, $args ) {
Changing that line to the following should make the error disappear:
function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {

Great Tip but in menu description it does not support html tags. can anyone know about this?
Thanks
Iryna
Hi Guys,
Any ideas how to allow html tags in the description?
remove_filter(‘nav_menu_description’, ‘strip_tags’);
this one not work for me.
Damien Carbery
@Iryna: Can you post your code somewhere e.g. pastebin.com.
Where you call remove_filter() will determine whether it works – it has to be called after the add_filter() call.
Calling it just before the wp_nav_menu() call might work.
Max
Is there anyway for the description not to be hyperlinked?

Thank you so much for this tutorial. It was recommended to me and it worked perfectly for making the changes I wanted to make. However, in making these changes, I’ve lost my drop down sub-item menus. Any idea what affected that in the code change?
Thank you for your time and tutorial

It seems like a CSS issue, we are sorry we couldn’t be more specific. Try using Google Chrome’s developer tools to debug it.

I have implemented the menu descriptions and it worked great. Now my client is asking for a line break within one of the descriptions. I have tried putting a carriage return and inserting a tag into the description field through the admin. It doesn’t appear in the front end. WP removes these edits. Is there a way to remedy this?
WPBeginner Support
If your client just wants spacing then you can use CSS for that.
Admin
Paul Renault
The client wants a line break. Is there a way that I can insert a tag in the description? If I put one in now it gets removed.
Barry
Great tutorial guys, just want to know how to implement this on a custom menu displayed using the Custom Menu widget?
Oryan Consulting
Thank you! Been working on WordPress for years and I’ve never even heard of this before. I was looking to remove the descriptions as they were very redundant on the site I’m working on. I looked everywhere for where they were coming from.
Oh joy!
sambassador
works!
but for php 5.4 you’ll have to match the wp walker arguments for the start_el function:
function start_el( &$output, $object, $depth = 0, $args = array(), $current_object_id = 0 )
and find replace $item with $object.
Steve Covello
You Rock!! Worked perfectly.
Kevin Gilbert
Perfect. This was just what I needed to finish up on a site. I had some issues with the CSS, but I finally figured it out and got it working. Thanks for the great articles.

Excellent tip. Worked perfectly!

I needed to create same thing and I was totally lost.
I was planning to do some stupid things to get this thing done.
thank god I found this post and saved time and stress!
I simply love this site got to know so much things.
Thanks you so much for showing the easiest things here.
Pankaj
The span tag is coming on sub-menus too.
its not showing there but it is taking that much of space which makes it look too odd.
is there any workaround for the same??
DiTesco
This is really a great tutorial and I was wondering if this would work on the Thesis 1.8.5? If not, it would be great if you can provide one. I will most certainly help you put it out there. Thumbs up!
svet
I followed your tutorial and added description to my menu. Thanks! However, when I am in mobile mode menu converts into dropdown menu and menu title and description are connected. For example, if my menu item is “about” and description “more about me”, the mobile version shows “aboutmore about me”. Is there a way to fix this?
David
I had the same problem. Here’s what I did.
I changed this:
$description = ! empty( $item->description ) ? ‘<span>’.esc_attr( $item->description ).'</span>’ : ”;
To this:
$description = ! empty( $item->description ) ? ‘<br /><span>’.esc_attr( $item->description ).'</span>’ : ”;
Not sure if it’s the best solution, but it worked for me.
Garrett Hyder
Thanks guys, I ran into what SVET and DAVID did with the mobile menu.
The code seems to have changed my change was simply appending in a span with the dash seperator and in my desktop query simply suppressed it as was unneeded there.
$item_output .= ‘ – ‘;
Within my Desktop Only Query set the span to display none;
@media only screen and (min-width: 740px) {
header #submenu li span.dash { display:none; }
Hope that helps, handled my issue nicely.
Nicola
Great post – very clear, exactly what I needed and worked perfectly. Thank you!
Samedi Amba
Thanks for the Great Tutorial. I’ve done the major steps well, as you can see from

I was stuck with the styling-how do I reduce the space between the Main Menu Label and the description? Your help is greatly appreciated.
Editorial Staff
It has to do with the line-height of your .menu a class of your theme. If you reduce that, then the spacing will reduce itself.
Admin
Chris Rouse
Great post. I’ve tried to dig into this before but the previous instructions I found were not this easy to follow. I was able to drop the functions.php code in, figure out how to change the walker class in my header file (different for the theme I use, but straight forward), and get things going in about 15 minutes from start to finish.
One piece that you might want to add is how to include the right border on the last menu item using the :last-child property.
.menu-item:last-child {
border-right: 1px solid #ccc;
}
Damien Carbery
Instead of extending Walker_Nav_Menu it would be nice (and easier) if a filter was provided e.g.
If the core code had:
$item_output .= apply_filters( ‘walker_nav_menu_description’, $item->description);
Then the custom filter function would just have:
return ” . $description . ”;

Great info … going to start adding this to my sites. Thank you!
