I've created a custom WordPress menu using the WordPress walker function. I've managed to do all the necessary HTML I need except adding the top-level menu title to just after one of the divs in the "start_lvl" section in the function.
Output should look like this:
<ul>
<li><a href="#">Title</a>
<div class="mega-menu">
<div class="mega-menu-inner">
<h2 class="fz-40">DISPLAY TOP MENU TITLE HERE</h2>
<ul class="mega-menu-accordion-wrap">
<li class="mega-menu-accordion">
<a href="#"></a>
<div class="mega-menu-accordion-inner">
<ul>
<li><a href="#"></a>
<div class="sub-mega-menu-wrap">
<ul>
<li><a href="#"></a></li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</div>
</li>
</ul>
This is what I have so far for the WP nav walker:
wp_nav_menu( array(
'theme_location' => "header-menu",
'walker' => new WPDocs_Walker_Nav_Menu() ) );
/**
* Custom walker class.
*/
class WPDocs_Walker_Nav_Menu extends Walker_Nav_Menu {
/**
* Starts the list before the elements are added.
*
* Adds classes to the unordered list sub-menus.
*
* @param string $output Passed by reference. Used to append additional content.
* @param int $depth Depth of menu item. Used for padding.
* @param array $args An array of arguments. @see wp_nav_menu()
*/
function start_lvl( &$output, $depth = 0, $args = array() ) {
// Depth-dependent classes.
$indent = ( $depth > 0 ? str_repeat( "\t", $depth ) : '' ); // code indent
$display_depth = ( $depth + 1); // because it counts the first submenu as 0
$classes = array(
'sub-menu',
( $display_depth % 2 == 0 ? 'menu-odd' : 'mega-menu-accordion-wrap' ),
( $display_depth >=2 ? 'sub-sub-menu' : '' ),
'menu-depth-' . $display_depth
);
$class_names = implode( ' ', $classes );
// Build HTML for output.
if( $display_depth === 1):
global $title;
$output .= '<div class="mega-menu">';
$output .= '<div class="mega-menu-container-wrap">';
$output .= '<div class="mega-menu-help-bar"><figure> <img src="'.get_template_directory_uri().'/svg/search-white.svg" alt=""></figure><a href="#">Need some help?</a></div>';
$output .= '<div class="mega-menu-inner">';
$output .= '<h2 class="fz-40">Need the Title Here''</h2>';
$output .= "\n" . $indent . '<ul class="' . $class_names . '">' . "\n";

$output .= "\n" . $indent . '<div class="sub-mega-menu-wrap">' . "\n";
$output .= "\n" . $indent . '<ul class="' . $class_names . '">' . "\n";

}
}
Solved this shortly after my post, for anyone who requires this, I did the following:
Add this to the functions.php file:
function add_menu_title( $item_output, $item, $depth, $args ) {
global $menuTitle;
$menuTitle = $item->title;
return $item_output;
}
add_filter( 'walker_nav_menu_start_el', 'add_menu_title', 10, 4);
Then in your header template just add this to the section you would like it display. In my example I updated the depth===1 to the following:
if( $display_depth === 1):
global $menuTitle;
$output .= '<div class="mega-menu">';
$output .= '<div class="mega-menu-container-wrap">';
$output .= '<div class="mega-menu-help-bar"><figure> <img src="'.get_template_directory_uri().'/svg/search-white.svg" alt=""></figure><a href="#">Need some help?</a></div>';
$output .= '<div class="mega-menu-inner">';
$output .= '<h2 class="fz-40">'.$menuTitle.'</h2>';
$output .= "\n" . $indent . '<ul class="' . $class_names . '">' . "\n";
