How to access one item from the menu?

Question

HTML

There is a code that should add data-toggle to only one item from the menu,

add_filter('wp_nav_menu_items', 'add_data_target_to_wp_nav_menu_items');
  function add_data_target_to_wp_nav_menu_items($items) {
        return str_replace('<a ', '<a data-toggle="modal"', $items);
}

, but due to my ignorance in this matter, it applies to all tags and on the page, how can you refer to an element, let's say by id, or by its href value?

Answer 1

Your filter gets an array with all menu items. Do a var_dump($items) and see what properties they have and how to get to the css-id or css-class (you can give them in the admin). And then through foreach find the desired item
