    You can use this hook to add HTML elements into the <a> tag of a specific type of nav menu item.
    For example, if you have items in the nav menu that act as dropdown menus, you may want to add a HTML element that displays a downward arrow beside only those menu items, while keeping the other menu items unchanged.

    If you just want to add something to the end of all menu items, you can instead use the after or link_after arguments when calling wp_nav_menu().


     * Add a dropdown arrow in the navigation menu, for menu items that 
     * have a dropdown sub-menu. Returns all other menu item titles unchanged.
     * @param string   $title     The menu item's title.
     * @param WP_Post  $menu_item The current menu item object.
     * @return string
    function wpdocs_nav_menu_add_dropdown_arrow( $title, $menu_item ) {
    	$menu_item_classes = $menu_item->classes;
    	// If menu item doesn't have any classes or children, return unchanged title.
    	if ( empty( $menu_item_classes ) || ! in_array( 'menu-item-has-children', $menu_item_classes ) ) {
    		return $title;
    	// Add div around original text to separate it from down arrow 
    	// (if you need a way to select only the text with CSS)
    	$output_title  = '<div class="menu-item-has-children-text">';
    	$output_title .= $title;
    	$output_title .= '</div>';
    	// Add downward arrow HTML
    	$output_title .= <img src="./downarrow.jpg" />; 
    	return $output_title;
