System menu WordPress ma wbudowaną funkcję, dzięki której można dodawać opisy do pozycji menu. Funkcja ta jest jednak domyślnie ukryta. Nawet gdy jest włączona, wyświetlanie ich nie jest pomocne technicznie bez dodania kodu. Większość motywów nie została zaprojektowana z myślą o opisach pozycji menu. W tym artykule pokażemy, jak włączyć opisy menu w WordPress i jak dodać opisy menu w twoim motywie WordPress.
Uwaga: Ten poradnik wymaga znajomości HTML, CSS i tworzenia motywów WordPress.
Kiedy i dlaczego warto dodawać opisy menu?
Niektórzy użytkownicy uważają, że dodanie opisu menu pomoże w SEO. Uważamy jednak, że głównym powodem, dla którego warto z nich korzystać, jest oferowanie lepszych wrażeń użytkownikom na twojej witrynie.
Opisy mogą być używane do informowania odwiedzających, co znajdą po kliknięciu pozycji menu. Intrygujący opis przyciągnie więcej użytkowników do kliknięcia menu.
Krok 1: Włącz opisy menu
Przejdź do Wygląd ” Menu. Kliknij przycisk Opcje ekranu w prawym górnym rogu strony. Zaznacz pole Opisy.
Spowoduje to włączenie pola opisów w twoich pozycjach menu. Na przykład:
Teraz możesz dodawać opisy menu do pozycji w twoim menu WordPress. Jednak opisy te nie pojawią się jeszcze w twoim motywie. Aby wyświetlić opisy menu, będziemy musieli dodać trochę kodu.
Krok 2: Dodaj klasę walker:
Klasa Walker rozszerza istniejącą klasę w WordPress. Zasadniczo po prostu dodaje linię kodu do wyświetlania opisów pozycji menu. Dodaj ten kod w pliku functions. php twojego motywu.
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 );
}
}
.
Krok 3. Włącz Walker w wp_nav_menu
Motywy WordPress używają funkcji wp_nav_menu() do wyświetlania menu. Opublikowaliśmy również poradnik dla początkujących na temat dodawania własnych menu nawigacyjnych w motywach WordPress. Większość motywów WordPress dodaje menu w szablonie header.php. Możliwe jednak, że twój motyw używał innego pliku szablonu do wyświetlania menu.
Teraz musimy znaleźć funkcję wp_nav_menu( ) w twoim motywie (najprawdopodobniej w header.php) i zmienić ją w następujący sposób.
<?php $walker = new Menu_With_Description; ?> <?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu_class' => 'nav-menu', 'walker' => $walker ) ); ?>
.
W pierwszym wierszu ustawiamy $walker na użycie klasy walker, którą zdefiniowaliśmy wcześniej w functions.php. W drugim wierszu kodu jedynym dodatkowym argumentem, który musimy dodać do naszych istniejących argumentów wp_nav_menu jest 'walker' =>$walker.
Krok 4. Stylizacja opisów
Klasa Walker, którą dodaliśmy wcześniej, wyświetla opisy przedmiotów w tym wierszu kodu:
$item_output .= '<br /><span class="sub">' . $item->description . '</span>';
.
Powyższy kod dodaje podział wiersza do pozycji menu poprzez dodanie znacznika
. <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">Who are we?</span></a></li>.
.
Aby zmienić sposób wyświetlania opisów na witrynie, możesz dodać CSS w arkuszu stylów twojego motywu. Testowaliśmy to na Twenty Twelve i użyliśmy tego css.
.menu-item {
border-left: 1px solid #ccc;
}
span.sub {
font-style:italic;
font-size:small;
}
.
Mamy nadzieję, że ten artykuł okaże się przydatny i pomoże ci stworzyć fajnie wyglądające menu z opisami w twoim motywie. Pytania? Zostaw je w komentarzach poniżej.

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?

thanks…it worked. but in menu description it does not support html tags.

You expain very well – detailed and clearly. 1 minute and menu items descriptions are ok. Thank you!
Mary Anne
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
WPBeginner Support
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.

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.
Jon
Excellent tip. Worked perfectly!
Jedediah White
This worked perfectly for me. The class function is perfect too. Thanks a lot!

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.

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!
