I don't really get your point. Can you explain more clearly what you would like to achieve!?

lol sorry did you test it (its joke)?
no sense to click on "add item link menu" in an item form and need to select type, name etc ...
when you you clic on buy did you need to reselect article in cart ??
it will be automatic

I do not understand either.
If you edit or create an item - which item? A Menu Item for a Menu? While editing a Item, it is not possible to click on "new item" this button exists only on lists.
Could you give a screenshot?

Thank you ... got it. The item is an article ..

Yes sorry that the same workflow for category thanks @brianteeman for gif

Its a bug not a missing feature

The code does not create at all a single article menu item.
It just loads the menu item modal. Only the language would already be filled in case of multilingual site and the item has a language set.

				// Setup variables for display
				$linkSuffix = '&layout=modal&client_id=0&tmpl=component&' . Session::getFormToken() . '=1';
				$linkItem   = 'index.php?option=com_menus&view=item' . $linkSuffix;

				// Force the language of the menu item when multilang is implemented
				if (Multilanguage::isEnabled() && $this->form->getValue('language') !== '*')
				{
					$linkItem .= '&forcedLanguage=' . $this->form->getValue('language');
				}

				$urlNew  = $linkItem . '&task=item.add';

Thanks for checking code @infograf768

i think we need to finish this feature ... or remove add link to menu button because no sense to add information x2

Closing as this has been resolved elsewhere and is no longer reproducable
