Create the function
So I created a new custom walker function in functions.php and copied all the code of the core wp nav walker function (wp-includes/class-walker-nav-menu.php).
Check for a menu item that has children
I then added this array_search in public function start_el to check if the parent element has the class "menu-item-has-children":
$has_children = array_search ( 'menu-item-has-children' , $classes );
Output the toggle button
I then output the collapse element at the end of the start_el function if $has_children is true:
if($has_children != false) :
$item_output .= '<div class="toggle-button"></div>';
endif;
Making it all work
I then added jQuery to toggle a class on the parent element of the toggle button.
jQuery(".toggle-button").click( function (){
$(this).parent().toggleClass("menu-collapsed");
});
This works perfectly, but is there a better way to check if the menu item has children? Searching for a class name just doesn't feel like the best solution.
jQuery(document).ready(function() {
jQuery("span.icon").click(function (){
jQuery(this).parent().toggleClass("menu-collapsed");
if(jQuery(this).parent().hasClass('menu-collapsed')) {
jQuery(this).parent().find('ul.sub-menu').first().css("visibility", "visible");
}
else {
jQuery(this).parent().find('ul.sub-menu').first().css("visibility", "hidden");
}
});
});
jQuery(document).ready(function() {
jQuery("span.icon").click(function (){
jQuery(this).parent().toggleClass("menu-collapsed");
if(jQuery(this).parent().hasClass('menu-collapsed')) {
jQuery(this).parent().find('ul.sub-menu').first().css("visibility", "visible");
}
else {
jQuery(this).parent().find('ul.sub-menu').first().css("visibility", "hidden");
}
});
});
