function _patterns_menu_parent_options in Patterns 6

Same name and namespace in other branches

1. 6.2 patterns.module \_patterns_menu_parent_options()

Custom implementation of Drupal's menu_parent_options()

Used to override static caching in menu_tree_all_data() which is preventing menu items created during patterns execution to be included in 'parent item' dropdown and causes validation errors. Hopefully, we can find better solution for this.

  // allow contrib modules to provide more scalable pattern choosers.

  // retrieved here, unless menu_override_parent_selector is set to TRUE.
