Is there a way to add field(s) to menu links in Drupal 8? Like an image field to output above certain links?

Could you specify the use case a bit ? The image field should come from a related node somehow or ?– Oleg VidenovMar 23, 2017 at 22:53

When creating a menu link in the menu admin, there would be a field for attaching an image to it, for rendering in say, a mega menu.– KevinMar 23, 2017 at 22:54

Ah, i see. So you need something like drupal.org/project/menuimage or drupal.org/project/menu_icons for D8.– Oleg VidenovMar 23, 2017 at 23:30

@OlegVidenov I only see D7 versions for both of those modules...– No SssweatMar 24, 2017 at 2:54

Add this code to your custom module:
function my_module_entity_base_field_info(\Drupal\Core\Entity\EntityTypeInterface $entity_type) {
if ($entity_type->id() === 'menu_link_content') {
$fields['menu_link_image'] = BaseFieldDefinition::create('image')
->setLabel(t('Menu link image'))
->setDescription(t('Upload the image related to this menu item'))
->setDisplayOptions('form', array('type' => 'string', 'weight' => 0));
return $fields;
}
}
Then use hook_update_n to update the schema of the menu_link_content_data table. Run update.php, flush caches and the new field should appear on all the Add/Edit menu item form.
In case someone wants to simply add a text field, boolean etc, simply edit BaseFieldDefinition::create('image') and change it to BaseFieldDefinition::create('string') or BaseFieldDefinition::create('boolean') etc
