Generate a custom structure for Wordpress menus.

This gist is for showing an example of a custom wordpress menu.

If you want to get more from the menu item simply have a look at the $item object. i.e:

// Will return a large object with lots of props like title, url, description, id etc.
var_dump( $item );

This code works on Wordpress 4.1.1 as of 31st of March 2015

<?php
$menu_name = 'main_nav';
$locations = get_nav_menu_locations();
$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );
$menuitems = wp_get_nav_menu_items( $menu->term_id, array( 'order' => 'DESC' ) );
?>
<nav>
<ul class="main-nav">
<?php
$count = 0;
$submenu = false;
foreach( $menuitems as $item ):
$link = $item->url;
$title = $item->title;
// item does not have a parent so menu_item_parent equals 0 (false)
if ( !$item->menu_item_parent ):
// save this id for later comparison with sub-menu items
$parent_id = $item->ID;
?>
<li class="item">
<a href="<?php echo $link; ?>" class="title">
<?php echo $title; ?>
</a>
<?php endif; ?>
<?php if ( $parent_id == $item->menu_item_parent ): ?>
<?php if ( !$submenu ): $submenu = true; ?>
<ul class="sub-menu">
<?php endif; ?>
<li class="item">
<a href="<?php echo $link; ?>" class="title"><?php echo $title; ?></a>
</li>
<?php if ( $menuitems[ $count + 1 ]->menu_item_parent != $parent_id && $submenu ): ?>
</ul>
<?php $submenu = false; endif; ?>
<?php endif; ?>
<?php if ( $menuitems[ $count + 1 ]->menu_item_parent != $parent_id ): ?>
</li>
<?php $submenu = false; endif; ?>
<?php $count++; endforeach; ?>
</ul>
</nav>

Hello.
Add a description menu ?

@theodorocaliari

Hi, before all, thanks for share your solution! Very apreciated!
Well, how can I add more 2 deep levels in sub menu? I tryed to copy and paste the fragment of 'ul.sub-menu' inside of the child 'li' but all is duplicated... =(

How can I do that? Please help me! Thanks!

@hitautodestruct

@theodorocaliari This code should drill down to any level sub menus.

@SpartakusMd

Hi. Your code is buggy. If you add a category to menu a error is shown. $page->post_title change with $item->title and $link = get_page_link( $id ) with $link = $item->url;. Also $page->post_excerpt won't exist.

@karlhadwen

SpartakusMd is right. I have to add that you must also have an 'isset' on both '($menu_items[$count + 1]->menu_item_parent)' pieces of code, or you'll get a property of non-object error. Also on the first 'isset' since you're closing the '' tag, make sure you use an else statement to close the tag even if it isn't set, or else you'll be missing a closing tag. I also tested it to multiple levels but it doesn't go that far.

@beesmart

I've run into a problem this code, it works great until you need to add a 3rd level menu-item, at which point the html elements come undone and the child menu items don't show up. I've checked the code to see what could be causing this or what I could do to fix it but to no avail. I've posted a questions here:

http://wordpress.stackexchange.com/questions/173573/wp-custom-nav-menu-problem

If you have any advice/help I'd greatly appreciate it.

@mashro3na

its worked with me by change

$page = get_page( $id );
$link = get_page_link( $id );
to
$title = $item->title;
$url = $item->url;
$class = $item->classes[0];

good work you saved my day! Thank you.

@karlhadwen

@mashro3na can you elaborate? you can't just replace two variables. @hitautodestruct can you fix this?

@hitautodestruct

@karlhadwen Replaced in gist 😄

@Valonix

if you add menu item like "LINK" you get a issue

@dmmarmol

@hitautodestruct I had the same issue that @theodorocaliari. I can't print more than one submenu list and I need to nest every <ul class="submenu"> inside a parent <li>, depending on how much submenu i have.

How can i evaluate the php( $parent_id == $item->menu_item_parent ) when the $item it has more than one parent element?

@SimonBak

Hello,

Thanks for your nice work.
Do you have an idea if i ant to add a third level more ?
Thanks.

@gnowland

@beesmart, you're absolutely right, there's an error in the code.

Line 41 should be:

<?php if ( !isset($menu_items[ $count + 1 ]) || $menuitems[ $count + 1 ]->menu_item_parent != $parent_id && $submenu ): ?>

and Line 47 should be:

<?php if ( !isset($menu_items[ $count + 1 ]) || $menuitems[ $count + 1 ]->menu_item_parent != $parent_id ): ?>

@hitautodestruct you may want to update this in the gist.

@loorlab

@gnowland & @hitautodestruct Thanks for your solutions !

@dagobertrenouf

@gnowland there's an error in your correction, it should be $menuitems[ $count + 1 ] instead of $menu_items[ $count + 1 ]

@michellomp

I made changes of @gnowland and @dagobertrenouf but the problem is the same i only get one level drop down menu
Does anybody succeed having multi level menu with this code
