I have seen the post on how to create menu items programmatically in Drupal 8, but how do I update or delete menu items in D8?

Clarification: by programmatically I mean dynamically so yaml config files are not going to help.

First you will have to load the entity. Either way works:

$menu_link = MenuLinkContent::load($menu_link_id);

or ...

$menu_link = \Drupal::entityTypeManager()->getStorage('menu_link_content')->load($menu_link_id);

Next you can update value using set() method or through the magic method __set...

$menu_link->expanded = TRUE;

To save, simply call the save() method. To delete, simply call the delete() method.

    You are using a mlid there, might seem like I am appending an additional question but where would you get that from, ie. how do you traverse a menu's tree? – Duncanmoo May 4 '17 at 12:20
  • In which hook we need to do all these? I am creating a theme and I override menu--main.html.twig file to style the menu. This code has to go in .theme file? in which hook? – siddiq Dec 11 '17 at 1:37

I had to do some thing like ....

 
 //menuLinkManager = 'plugin.manager.menu.link'
$result = $this->menuLinkManager->loadLinksByRoute('entity.node.canonical', ['node' => $node->id()]);
foreach ($result as $menu_item) {
          if (is_object($menu_item)) {
            $id = $menu_item->getPluginDefinition()['metadata']['entity_id'];
$menu_link = $this->entityTypeManager->getStorage('menu_link_content')->load($id);
$menu_link->enabled = 0;
$menu_link->save()

Probably too late I did like:

$menu_handler = \Drupal::service('menu.link_tree')
    ->load("menu-name", new \Drupal\Core\Menu\MenuTreeParameters());
foreach($menu_handler as $key=>$value) {
  if('Name' == $value->link->getTitle()) {
    $link = $value->link;
    $link->updateLink(
      [
        'enabled'=>'1',
        'title'=>'New Name'
      ],
      true
    );
  }
}
