protected function MenuForm::buildOverviewForm in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 core/modules/menu_ui/src/MenuForm.php \Drupal\menu_ui\MenuForm::buildOverviewForm()

Form constructor to edit an entire menu tree at once.

Shows for one menu the menu links accessible to the current user and relevant operations.

This form constructor can be integrated as a section into another form. It relies on the following keys in $form_state:

• menu: A menu entity.
• menu_overview_form_parents: An array containing the parent keys to this form.

Forms integrating this section should call menu_overview_form_submit() from their form submit handler.
